So I’m completely new to Salt Water so that’s why the title of this thread sounds so basic. But I’m tryna switch my FOWLR tank to a reef tank. It’s a 20g long (30”) and I was thinking of buying a coralife t5 light that’s 30”. Do y’all recommend this light ( the guy I’m buying from is only selling it $50 preowned) or should I buy a new led light. Also to note I’m on a strict budget so I can’t go out and buy an expensive fancy light like I want.
