Ive been into sps for a lil while now. I've gotten good growth from my stonies but I know I'm lacking some color. I see tanks on here where the colors are awe inspiring and can't help but wonder what fellow reefers do to get that effect. I've been messing around with nutrients and what not no3 po4, dosing aminos and feeding, but I'd like to know what you guys feel is the key to great colors in your corals. I hope some heavy hitters pop up on here!
