Simple, Urea and NH4 waste. Plant tanks can handle only so much with out
setting off algae hell. We are specifically NO3, not NH4. I mean algae hell.
I recently added a ton of fish into a twenty gallon to try this out. Every
thing I did could not prevent algae(a number of types appeared).
Herbivores,water changes you name it. Had to remove the fish.

Not one bit dumb. It's asked often enough and is valid. No dumb questions
really. I got plenty of dumb answers waiting though:)
