Thanks for the reply. My tank is a fowlr
and I see a lot of comments that the standard 40 watt chepo unit that I have is fine and in fact, more light than that can reduce Coraline growth.
I see tes 120.00 units at places like petsmart that are led
with timer for moon light etc. I'm thinking for my setup, this should work? If I go corals, that's a new ball game.
