Its a 55 gallon FRESHWATER planted tank. Red Mangroves.
The only fertilizer is the cichlid and pleco poop. Nitrogen is not a problem in this case, unless I do move them to a dedicated tank. I have not checked Mg, but is it important since mine are being grown in FW? As I understand it, mangroves get rid of sodium by taking in Mg, but I have only trace levels of Na and Mg in this tank.
Root growth has been disappointing though as they have just recently sent out the hair like roots. It seems mine went to growing leaves first. I was hoping to get more root growth so I could begin growing prop roots.
It might be time to move them to a more dedicated tank. If I do that, my fish are in my room, in the basement, no natural light, what should I consider lighting it with?
