***At this time, we are suspending the “program” part of our Fish-less Cycling Program due to reduced staff availability. Signups will not be accepted until further notice. If you are setting up a new jellyfish aquarium, we still strongly recommend you still cycle it using the fish-less method before introducing your first jellyfish.***

Thanks for your interest in our Fish-less Cycling Program! This program was set up back in 2016 for two reasons: 1) to help new jellyfish owners have a successful start with their new aquariums, and 2) clear up misinformation floating around the internet about the cycling process and how long it takes to successfully cycle a new aquarium. Cycling a new aquarium takes time, patience, and attention to detail but it ensures your new aquarium is biologically stable and habitable for any saltwater animal; this is not jellyfish-specific issue! This blog post provides the essential information you need to know about what cycling is and how to cycle your new aquarium. At the bottom of this post (after you’ve read every bit of information and become a cycling expert, of course!), you’ll find the sign up form to participate in our Fish-less Cycling Program.

A “fish-less cycle” is the best and safest way to cycle an aquarium, as it doesn’t harm any fish or jellyfish. The goal of cycling a new tank is to establish a healthy and strong colony of beneficial bacteria in the filters to take care of waste that is created by feeding the animals (in this case, jellyfish!).  The process of cycling a new aquarium is often overlooked and can create problem right from the get-go. New jellyfish owners who do not allow their tank to completely cycle before adding their first jellyfish sadly end up with unhealthy & deformed jellyfish and become confused about why they are not well. Since jellyfish are 96% water, they rely heavily on water chemistry (a.k.a. water quality) and therefore, need a biologically stable and “chemically clean” environment in order to thrive.

Cycling takes no less than 4 weeks. There is misinformation going around the Internet about how long cycling takes. Some websites claim “it only takes 10-14 days” or “two weeks.” This is wrong.  The nitrogen cycle is straight forward biology and you can’t speed up biology.  Even with the use of “bio-starters,” you must still cycle the aquarium and it will still take 4 weeks minimum.

 Now, let’s get to what it actually means to cycle your  new aquarium!

Cycling is turning a static, non-living environment (i.e. brand new tank/filters) into a biologically stable environment that’s safe for live animals.

What do we mean when we keep saying, “biologically stable environment”? Well, the filters (i.e. bioballs, rock media, etc.) of an aquarium need to have strong, healthy colonies of beneficial bacteria established within them. Beneficial bacteria = good bacteria! They take care of the waste created from daily feedings. Cycling allows these bacteria to establish themselves by multiplying and creating large colonies able to handle the waste created within your aquarium by the fish and the food being fed daily.

The Nitrogen Cycle: This is a three-step process converting ammonia (NH₃) into nitrite (NO₂) and finally into nitrate (NO₃)– all done through the bacteria. The “cycling process” is essentially the “nitrogen cycle”! All three of these compounds will be present at some point during cycling and since ammonia and nitrite are toxic to all saltwater animals (not just jellyfish), this is why cycling should be done “fish-less” and before introducing the first animals. Nitrate is a by-product of the nitrogen cycle that will always be present in your aquarium and is not toxic to moon jellyfish under 100 ppm; so, no need to worry about nitrate while cycling! It is always maintained through weekly water changes once cycling is done.

Fish-less cycling involves placing a nickel-sized (approx. ¾” x ¾”) piece of raw shrimp (add one nickel-sized shrimp piece for every 10g of water volume your aquarium can hold) into the filter box or compartment of your aquarium. The raw shrimp will begin to decompose and create ammonia to start the cycling process. At the same time, a starter bacteria culture is added to begin the colonization in the filters. After about two weeks, the ammonia level will rise to a peak (also known as “spiking”) and then start to decrease to zero. Once the ammonia is finished spiking, the nitrite level will begin to rise. After another two weeks, the ammonia will return to zero and the nitrite won’t be far behind. Once the ammonia and nitrite levels both return to zero, the aquarium is cycled!

Let’s move onto the

Fish-less Cycling Program!

 Here’s what you’ll need to start:

  • Freshly mixed or store bought saltwater
  • Bacteria source – we recommend using BioSpira [Purchase from Amazon here]
  • Ammonia source – a nickel-sized piece (¾” x ¾”) of a raw shrimp for every 10g saltwater
    • Single shrimp can be bought from the fresh seafood section of your local grocery store
  • API Saltwater Master Test Kit – includes pH, NH3, NO2, NO3 [Purchase from Amazon here]
  • Thermometer and hydrometer or refractometer – to test for temperature and salinity
  • Fish-less Cycling Program Guidelines – this is your weekly guide to see what the *expected* week-by-week changes in water quality (also a.k.a. the nitrogen cycle) for your tank [download the PDF below]

Let’s start cycling!

  1. Once your new aquarium is set up and running with new saltwater (salinity should be 1.022-1.024 Specific Gravity or 31-33ppt), add the bacteria source and two nickel-sized pieces of shrimp at the same time.
  2. Take your baseline water quality readings – this includes temperature, salinity, pH, ammonia, and nitrite.
  3. Test for pH, ammonia, and nitrite every week to keep track of the fluctuations in levels that indicate where you are in the cycle. Record these on the PDF guideline water quality sheet (download below).
  4. Once both ammonia and nitrite have returned to zero after subsequent spikes, your aquarium is ready for jellyfish! (Keep the piece of shrimp in your aquarium until the jellyfish arrive. It will continue to feed the newly established beneficial bacteria until you begin a daily feeding routine with jellyfish).

DO’s & DON’T’s of Cycling

  • DO read this entire blog post and the Fish-less Cycling Program Guidelines to fully understand the cycling process and how to cycle your new jellyfish aquarium
  • DON’T skip any part of this blog as it contains all of the essential information you need to know about cycling!
  • DO use new saltwater with the following baseline water quality parameters:
    • Temperature = 65-78°F
    • Salinity = 31-33 ppt or 1.023-24 SG
    • pH = 8.0-8.1
  • DON’T add any buffers, conditioners, or additives to your aquarium water before or during the cycle – these can throw off the water quality and disrupt or inhibit the cycle from starting
  • DO use Instant Ocean Sea Salt mix for your saltwater as it has no buffers, conditioners, or additives [Purchase from Amazon here]
  • DON’T use any salt mix labeled as “reef salt,” “pH balanced,” “probiotic,” or “enriched” as these tends to have extra minerals, vitamins, and higher levels of pH specific for corals, anemones, etc. in reef tanks
  • DO make sure your pump is plugged in, turned on, and working properly
  • DON’T keep your tank near windows and/or in direct sunlight to keep algal growth at a minimum
  • DO use freshwater labeled only as “Distilled Water”
  • DON’T use freshwater jugs labeled “Spring Water,” “Purified Water,” or anything else to mix your saltwater or for topping off
  • DO add distilled/RO water to compensate for evaporation (evaporation causes salinity to rise; adding freshwater helps to bring it back down)
    • Evaporation is noticeable when the water level is lower than where it started
  • DON’T add distilled/RO water near the filters – this can completely wipe out your growing bacteria colonies
    • Only add freshwater to the main viewing area
  • DO record your weekly test vial readings via pictures with the color chart
  • DON’T use test strips as they often give unreliable readings
  • DO start the cycling process with a newly setup aquarium.
    • If your aquarium has been running with saltwater & the bio starter bacteria for longer than a week, you will need to dump the water and start over with all new saltwater & new bacteria.
  • DON’T perform any water or filter changes during cycling – this can disturb the growing bacteria and disrupt the cycle
  • DO keep an eye on the piece of shrimp in your tank – sometimes it can completely disintegrate before the cycle is over and will need to be replaced to keep the ammonia production up
  • DON’T freak out if your cycle isn’t exactly on track – every cycle is different and sometimes an aquarium needs an extra week to catch up
  • DON’T add a bubbler if you own a Cubic Orbit 20 jellyfish aquarium before or during the cycle – aeration can inhibit the cycle from starting

Things that can delay or disrupt the cycling process

  • Starting with a pH higher than 8.2 can inhibit the cycling process from starting by disturbing the bacteria. The pH of an aquarium will naturally drop during the cycle – which is normal! – and needs to be left alone to do its thing until the cycle is done.
  • Starting with salinity too high or too low can also inhibit the cycling process from starting by disturbing the bacteria. The optimal salinity range for moon jellyfish is 31-33 ppt or 1.023-24 SG, which is perfect for cycling.

Acclimating Your Jellyfish in 4 Easy Steps

by sunsetmarinelabs, posted in Acclimation, Feeding & Maintenance

Temperature Acclimation

Step 1.

Float the bagged jellies in your jellyfish tank until the temperature inside the bag matches your jellyfish tank water. This will take about 15-20 minutes, more or less.  Rotate and turn the bag occasionally to keep the jellies stimulated and belling. This helps mix the water inside the bag and expedite the process.

Step 2.

Take the temperature of the bagged water and compare it with that of your tank water. They should match before moving on to the next step.

 

Water Chemistry Acclimation

Once the temperature has equalized between the bagged jellies and the tank water, you can begin to conduct small water changes inside the bag. This is called water chemistry acclimation.

Step 3.

Exchange water between the bag and your tank water. Open the bag and pour out (or scoop out using a small plastic cup) about 20% of the water in the bag. Then gently allow about 20% of your tank water into the bag, secure with the rubber band and allow it to float once again. You can leave some air in the bag as you band it up so it floats well. Still rotate and turn the bag to gently stimulate the jellies to bell and therefore move the newly introduced saltwater through their system. They must be actively moving the water through their system in order to properly acclimate and they need you to help them do it. Gently spin, turn & rotate the bag with each water change.

You will do 4 or 5 of these small water changes over an hour. Pour a little water out of the bag and then introduce a little water back into the bag—you are slowly and gently getting your jellies comfortable with their new watery environment. Do not rush this step. It is crucial to your jellies survival and development. Please complete it within 1-2  hours total time from temperature acclimation until introducing them into your tank.  (i.e. don’t spend all day getting them acclimated… they do need to get out of the bag in a timely fashion).

 

Step 4.

Releasing the Jellies into your Tank

• Now that you have properly acclimated the jellies, you should see nice and even belling inside the bag.  Now you can release them into the tank.

• Leave the bag sitting in the water.

• Gently open the bag.

• Allow the jellies to exit the bag.

• Do not spill the jellies into the tank.

Do you love keeping fish and would also like to keep jellyfish?  What to do?!

You can keep them both in our Eon Jellyfish System because we have a fully-functional wet/dry filter on the back of the tank! Once your system is cycled, you can safely add fish. They also love feeding on the jellyfish food …

We have been testing our Eon 2ube Jellyfish System with 3 Pajama Cardinal fish and a pair of Clownfish. Also hanging out in the tank are 15 moon jellies about 2″-3″ diameter.

Please note, this system is fully cycled and has a heater in it to maintain a constant temperature of 72-75ºF for these tropical fish.

Everyone has been getting along and thriving for the past six weeks and only being fed our jellyfish food. Next, we will add a sea anemone specifically for the clownfish, and see how that goes!

More to be revealed soon!  But we are super excited to have a co-habitation situation happening between the fish and the jellyfish! The clownfish are extremely interactive with us and seem very happy.  The pajama cardinals are super relaxed and love the jellyfish food!

 

 

 

 

5 Things That Can Cause Your Jellyfish to Disintegrate & Look Sad

by sunsetmarinelabs, posted in Keeping a Healthy Tank, Sick Jellyfish?
Do your jellyfish look like this? 

sadjelly3          sadjelly2        sadjelly1     

If they do, I’m sorry to hear that, but don’t despair just yet.  Once you determine the problem & fix it, the jellies can bounce back and repair themselves in no time!  Here are the top 5 reasons jellyfish will start to fall apart…

1. Improper filtration and/or incomplete cycling of your filters.
2. Ammonia spike.
3. Not Acclimating your Jellyfish Properly
4. Improperly making up your saltwater
5. Heavy metal contamination.
1. Improper filtration and/or incomplete cycling of your filters.

If you haven’t properly cycled your tank, then you most likely have toxic levels of ammonia and/or nitrite in your water.  This can happen when you initially set up an aquarium and add jellyfish (or any life forms, for that matter…this is not a jellyfish specific issue, but a standard fish or coral tank issue. You must take the time to properly cycle your aquarium no matter what animals you choose to keep in it). Once jellyfish are added to the tank, they begin to produce ammonia.  Once ammonia starts to build up, you need to have a way to eliminate it. This is why proper filtration is important.  A properly filtered aquarium will have a biological filter in place, which will remove the toxic ammonia and nitrite by way of the beneficial bacteria that populate the filter media (i.e. bio balls). If you do not have beneficial bacteria actively removing the ammonia and nitrite, then the water becomes toxic and the jellyfish will soon begin (within 2 days) to disintegrate like the pictures demonstrate.

Toxic Water Quality
Ammonia & Nitrite levels demonstrating the middle of a nitrification cycle. This is a very toxic situation. Jellyfish will fall apart if subjected to these levels of toxicity.
2.  Ammonia spike.

Why are you having an ammonia spike even after you’ve already cycled your tank?  An ammonia spike can occur if you stopped feeding your tank for any reason.  Sometimes folks let the aquarium go down, or let it run without any animals in it for awhile like if they go on vacation or take some time away from keeping jellyfish, or they don’t have jellies in it for several days for whatever reason. This leads to an ammonia spike because your beneficial bacteria in you filter box didn’t receive any ammonia to eat—your system wasn’t creating any ammonia because you had no jellyfish in it & subsequently weren’t feeding  any jellyfish. This means the beneficial bacteria went with out food (ammonia) and starved to death.  So, if you then add jellyfish to the tank when you get back from vacation (or whatever), there is no beneficial bacteria  available in the filter box to eliminate the toxic ammonia & you experience an ammonia spike and shredded jellyfish as the pictures show.

If you do go on vacation, or take more than 3 days away from having jellyfish in your tank, you can alway place a small, 1/4″ piece of raw fish or shrimp in the filter box to continue to decompose and create ammonia for the beneficial bacteria to feed on while you’re away.  When you return, always take an ammonia reading and remove the piece of raw fish or shrimp before adding new jellyfish to the tank.  Make sure your ammonia and nitrite levels are at zero before acclimating any new jellyfish into your tank.

An ammonia spike can also happen if you interrupted the cycling process by cleaning the tank, changing any mechanical or chemical filters, or conducted any water changes prior to the tank completely finishing its cycling process. Do not interrupt the cycling process. I know it’s tempting to want to get the sides & bottom of the tank clean. The algae growth can be unsightly, but remember, you are creating a living environment from a static one. Life can be messy! Let nature take it’s course and be patient– I know it’s hard, but it is necessary.  You can clean the tank all you want after the cycling process is over! If you interrupt the cycle, it can take almost 3 times as long to get it back on track an in a non-toxic state.  Be patient. It’s worth the wait!

3. Not Acclimating your Jellyfish Properly

You are receiving jellyfish that are coming from a pristine environment.  When you receive a shipment of jellyfish, the water quality parameters are most likely different from yours.  You must take the time to acclimate the jellyfish in the shipping bag to the temperature of  your system.  After 10-15 minutes of floating the bag so the temperatures equalize between the bag and your tank water,  acclimate them to your water quality (pH, salinity), by conducting small water changes in the bag over 45 minutes to 1 hour.  Don’t take all night doing this step.  The jellies need to get out of the bag and into a moving environment.  Acclimation shouldn’t take more than 1.5 hours from start to finish.  If it is taking longer than that, then there is another problem at hand that needs to be addressed.

4. Improperly making up your saltwater

If you are making up your saltwater with tap water, your jellyfish will fall apart.  Tap water has heavy metals in it that the jellyfish cannot tolerate. You must make up your saltwater with RO, RO/DI, or distilled water for it to be safe for jellyfish, much like a reef tank.

If you are not aerating your saltwater for at least 24 hours in a bucket with a small submersible pump, then you most likely are adding undissolved salts to your tank.  The jellies don’t do well with undissolved salts.  Please read our blog post that covers this topic in depth: “Problem with Your Jellyfish? Undissolved Salts Could be the Culprit” 

5. Heavy metal contamination.

Do not use metal utensils or tools with your saltwater jellyfish aquarium.  Only use plastic tools.  Always wash your hands before dealing with your jellyfish or handling the jellyfish food.  Zinc, brass, lead & petroleum products (sometimes found in soaps and lotions) will add heavy metals to your system.  The jellyfish will fall apart if you introduce them into the water.  Also, I should mention that aquarium heaters can get old– moreover, their seals  can get old and crack. This can allow water to leak into them where the metal heating coil is located and other metal parts.  If you have an old heater, check it for any visual signs of rust on the heating coil.  If you see rust, throw it away and purchase a new one.

Have you had an unusually long cycling process?  Are your new jellyfish shrinking fast even after the tank finally cycled?? Please read our blog post next week for answers.

5 Things That Can Cause Your Jellyfish to Shrink

by sunsetmarinelabs, posted in Sick Jellyfish?
Large Moon Jellyfish
Large 10″ diameter Moon Jellyfish– This jellyfish has been raised in one of our customers tanks from 3″ diameter to 10″ diameter solely on our Frozen Jellyfish Food (feeding once a day).

Are your jellyfish shrinking, getting thin and flattening out???

Here are 5 reasons why that might be…..

1. Feeding Non-nutritious food

One of the most common problems when keeping jellyfish is keeping them properly fed. Without a consistent supply of nutritious food, they will become weak and thin. Malnutrition causes listlessness and infrequent belling or pulsing, leaving you with inactive jellyfish that just float around the tank like pieces of tissue paper.  Not pretty. Not elegant. Not fun! Your solution is to feed them jellyfish food that is nutritious & to feed them the proper amount.  There are a lot of feeds on the market for fish and corals and you may think that they will work for jellyfish.  Not the case.  Reef Nutrition has some amazing feeds for filter feeders and some of what they have to offer are good supplements for jellyfish, but not strictly meant for a main food source.

2. You Are Not feeding Enough Food (of the nutritious kind)

Jellyfish are not goldfish & you cannot simply sprinkle some food in every other day or so. They need to eat each day and they need to get a good amount into their systems with each feeding.  See our blog post Knowing How Much to Feed Your Jellyfish for guidelines & pictures of what a well fed jellyfish looks like. Without enough good food to eat each day, they will become thin and lazy.

3. Your Flow is too High—or Too Low.

If your jellyfish aquarium has adjustable flow, you may need to fine tune it.  If the flow is too high, the jellyfish may not be able to keep the food on their tentacles as they whiz around the tank and this means they are not ingesting the food. This leads to underfed jellyfish, which leads to lazy and shrinking jellyfish.  The same goes for low flow.  If the flow in your tank is  so low that the jellyfish cannot properly bell and keep themselves suspended, then they will not feed properly.  Again, this leads to malnutrition and shrinking jellyfish.  Jellyfish need to bell efficiently in order to move fluids and food into and throughout their system.

4. Your Jellyfish Aquarium is Not Cycled

If your aquarium is not biologically cycled then your water quality is toxic (you have ammonia and/or nitrite levels above zero) and the jellies will be stressed because of it.  Jellyfish are 96% water, so if your water quality is suffering, so are your jellyfish.  They will not eat much, if at all, and this leads to shrinking jellyfish.

5. Your Salinity is Too High

When your salinity is too high, the jellyfish will cease to eat.  Keep your salinity in check–everyday if necessary–so your jellyfish can feed properly without the stress of spiking salinity levels.  If you haven’t yet read our blog post about hydrometers and the inaccurate readings they can give….read it now.  The plastic hydrometers on the market tend to have variable readings.  Have your hydrometer tested at your local fish store to be certain that yours is giving you accurate readings.  Again, if your jellyfish are not getting enough food each day, they will shrink.

 And a word about vacations, weekends & days off from feeding….

If your jellyfish are healthy and being fed normally and on a regular basis with nutritional jellyfish food, then you can safely get out of town for the weekend.  They will be fine given they have full stomachs 5 days out of 7.

Hungry Jellyfish with Empty Stomachs

It’s hard to regulate just how much food to feed your fish sometimes.  You don’t want to over feed them or under feed them.  But, how do you know if your jellyfish are getting enough to eat each day????? If only you could see just how full they were.  Hard to do with fish, BUT….you have jellyfish!!! They’re transparent!

You can see right through them & see their stomachs!  This is the best way to know if you’re feeding enough each day to keep them healthy and growing.

One of the most common problems when keeping jellyfish as pets is keeping them nutritionally fulfilled. Most folks are not sure just how much to feed to keep their jellyfish healthy.  Jellies are passive feeders and need more food than you think. They quickly become lethargic and thin if they aren’t getting enough good food to eat. So, if you start out not feeding enough nutritional food, your jellyfish will start to wither and shrink.

The picture below represents moon jellyfish that are waiting for a meal. Empty stomachs!

The picture below demonstrates what your jellyfish should look like about 45 minutes after feeding them.

Full Stomachs! Happy Jellyfish!

Their stomachs should be nice and full like this at least once a day, with nutritionally sound food for jellyfish.
