How much light am I going to need for the fuge. Can I use NO flourescent or do I need to get PC. Current USA makes a 1x65 PC and a 2x65 PC. What deg K should I be using for the fuge.
You should probably be fine with 55 watts. Macroalgae are supposed to like higher K values better, but I'm getting good growth under a 5500 K light right now.
