Sir charles, I have another piece of question. if it's okay
My current folwr lighting is only (1) 28 watt elongated 6200K daylight NO T8 and I believe it's not gonna make corals survive. I was thinking if I add 3 more fluorescent light with the same specification. What kind of algae can it make survive? I just want my FOLWR tank to look more beautiful by having plant like species.
