i understand that for a reef tank we need change water to replace the minerals/nutrients..etc.. for the corals..etc
but for a FOWLR tank ,is it possible to have a "dun need to change water" tank, if the Biological Filtration system is achieve in top quality/strength and/or is more than enough to maintain the bio load?
...
meaning
...the
beneficial bacteria population out numbers the bio-load placed on the aquarium.
