How to Make a Siphon Tube for Jellyfish Aquariums


By now you’re probably well acquainted with the silty material that accumulates at the bottom of your jellyfish tank. It often comes from uneaten jellyfish food, dust, algae or other particulate matter that might find its way into your system. This build up is perfectly normal and not harmful in small amounts, but it doesn’t make for pleasant decor! And you don’t want it to pile up too high, or you could run the risk of affecting your water quality.

The easiest way to deal with unwanted tank crud is to just suck it up! So here we’ll show you how to make a simple, narrow siphon tube specifically for tidying up your jellyfish tank.  Most siphon tubes on the market are for gravel vacuuming and have a 2″+ diameter.  That is much too big for jellyfish care!  You need a narrow siphon tube in order to work slowly around the jellyfish. You can find most of these parts at your local fish store or home improvement store.

What You’ll Need

– 1/4″-3/8″ (outer diameter) rigid plastic tubing (at least 2 feet for 10g EON, 3 feet for 20g 2UBE)

– flexible plastic tubing (at least 4 feet, maybe longer depending on how high off the ground your tank sits) to fit whichever size rigid tubing you find


– electrical tape (any color you like)


Step 1:

Join your rigid tubing to your flexible tubing to make the body of the siphon tube.



Step 2 (optional): 

If you’re working with a larger or taller tank, add an extra length of rigid tubing to the end of your siphon using a spare chunk of flexible tubing as a joint.




Step 3:

Wrap a couple inches of electrical tape around the very end of your rigid tubing so you can clearly see the end of the tube when you’re working. You don’t want to suck up your little jelly pals by mistake!

And voila! A siphon tube of your very own. Use it responsibly!

HINT: Once you have the siphon working, you can control the rate at which it removes water from the aquarium by simply pinching the flexible tubing.  You can also completely stop the flow of water in the same manner—just pinch or bend the flexible tubing.


DIY: Build Your Own Extension Scrub Brush for the EON 2ube and 3ON

Jellyfish Tank

If you have the Eon 20 gallon Jellyfish System, you may have had difficulty cleaning the bottom of the tank.  It’s easy to clean the sides of the tank with an aquarium cleaning magnet, but how to clean the bottom & back?  There are some extension scrubber brushes out there (the black unit on the left in the picture), but in our experience these tend to be in adequate. They do extend nicely but…..


The cleaning heads are minimal and after only 2 uses tends to fall apart.scrubrush2

You can easily and cheaply build your own scrub brush using a standard acrylic aquarium scrub brush purchased at any fish store & a couple 1/2″ PVC fittings, 1/2″ PVC pipe & electrical tape found at Home Depot, Lowes or any home improvement store.


What you will need:

8″ long piece of  1/2″ diameter threaded grey rod

4″ long piece of 1/2″ diameter PVC pipe

1 PVC fitting: 1/2″ coupling Slip x Slip

1 PVC fitting: 1/2″ coupling Thread x Thread

electrical tape

First thing you want to do is secure the 1/2″ PVC Thread x Thread fitting to the scrub brush handle using electrical tape.  Place the PVC fitting just below the hook on the scrub brush & using the electrical tape (about a 9″ long piece) secure the fitting to the scrub brush.  Electrical tape stretches nicely, so stretch and then pull on the tape to join the two together & then continue wrapping the tape around the fitting and the scrub brush handle like the picture. Make it snug and tight!


Now you can attach the  extension handles.  First, the threaded grey rod & then the white PVC pipe.


Lickety Split! Easy! And cheap!

DIY: Stop Your Turkey Baster from Dripping




If you have the Eon 10 gallon Jellyfish System, you may have been using a turkey baster to either feed your jellies or quickly pick up any detritus or uneaten food at the bottom of the tank, or both.  Most turkey basters drip terribly unless you seal the bulb to the pipette.  Once sealed properly the baster creates better suction and you can quickly and easily pick up any unwanted algae or uneaten food and deposit right away into the filter box–no dripping!  This makes for a quick tidying of the tank without having to pull out the siphon tube and do an entire water change.

Using a 5″ piece of electrical tape you can easily solve this problem.  Electrical tape comes in many lovely colors and has the unique characteristic of uniformly stretching and creating a nice watertight seal around the bulb and the pipette.

Step 1.

Cut a 5″ long piece of electrical tape.


Step 2.

Place the 5″ long piece of electrical tape half on the bulb and half on the pipetteturkeybaster2

Step 3.

Place your thumb on the electrical tape and hold it firmly while firmly pulling on the tape to stretch it.turkeybaster3jpg

Step 4.

Continue pulling the electrical tape tightly all the way around to create a nice seal like this!turkeybaster4This is easily removed & repeated when you need to clean the turkey baster once a month or so.
