So i managed to create a bioactive terrarium for my crestec gecko a couple of months ago, which seems to be working perfectly fine and has become stable. I know this is the wrong place to mention it, but is a bio-active aquarium such a thing? I was reading that the aquatic plants use the nitrates produced from the fish and create a balance in the tank so the water quality for the fish stays at a good level. I have a 10 gallon tank and would like to know your thoughts on it, or tips from someone who has made one before, or even attempted the project. Thanks.
