Hi guys, right now I have a 55gal low tech tank with a 48' double t5NO fixture. As for substrate I have flourite under gravel. My question today is whether i need to be adding any fertilizers to the tank on a daily/weekly basis considering it is low tech. Right now there appears to be no problem with plant growth except with my java moss, I recently noticed it starting to turn brown so i went and thinned it out so that the light reaches the bottom of the moss as well but it still doesn't seem to be doing any better. Also I am having a bit of trouble with algae growing on the glass but nothing incredibly bad at the moment. If I should be dosing any ferts please be sure to clarify which ones, how much, and how frequently. Also should I be adding liquid CO2? Thanks for the help in advance.
