Do all plants need added fertilizer?
I am considering doing a lightly planeted tank. Could Vallisneria Americana and Hygrophila difformis survive with out ferts. Also if not, are there even any that can? And if their are please recommend some. It is a 55 gallon tank(48Lx12Wx21H inches) With 2 54 watt t5ho bulbs 8 inches above the lip of the tank(what I believe to be medium lighting). Also they should be relatively hardy as I have firemouth cichlids(I know they dig) it seems like they don't eat plants but I have found a couple of people who say theirs did.
