Hi, I am thinking of changing my 120 gallon planted freshwater tank into a saltwater planted tank with caulerpa prolifera, blue ocho and dragons breath and red macros. I am currently growing them in my red sea 34 gallon seahorse tank and they are much easier than the planted tank, which still looks awful after years of trying and battling constant BBA. My red sea tank has power compact with a 55 watt 10000K and a 55 watt actinic, but what is the minimal lighting that will work?
