Are you having repeated issues with ammonia spikes even after cycling your aquarium? Does your filter box look like this?
EASY FIX!
Level your tank!
You can see from the picture that only a small portion of the filter is being used. This tells us that the water is flowing down the side of the filter box and not over the filter media. The water is bypassing all of your lovely filters! Therefore, you have no real filtration going on and will have unstable water quality because of it. That drip tray has holes in it so the water draining from the tank will be distributed OVER the filter media. You want the water to pass through the media in the filter box, not bypass it. The filters cannot remove any toxic wastes building up in your saltwater (i.e. ammonia, nitrite) if they don’t come in contact with it!
And remember, you will need to level the tank both left to right AND front to back!
With the lids removed, the level should be placed across the middle of the tank as shown in the pictures.
The bubble in a level needs to be exactly in the MIDDLE of the hash marks.
