For some reason I just had a visual of some poor guy who’s job it was to follow the little fish and catch their little poop’s for fertilizer.

Does fish poop float or sink or is it water neutral?

Here is how it works:

The fish poop is alkaline

The fish poop water goes through a filter bed populated with bacteria that live on the ammonia and poop nitrates

The nitrate loaded water then feeds the roots of plants that extract the nitrogen leaving clean water that is recycled back into the fish tank
