I have a 55 gallon. My substrate is sand. Its been set up for a few months now with some fish. I already have the lighting needed for a planted aquarium.
Since my substrate is already established I really dont want to pull it out to put a layer of that plant substrate down. Is this a must or is there some kind of tablet I can just put next to the roots?
I know about the liquid fertilizers but I just dont want the plants to suffer without anything in the substrate.
