OK sorry if the question has been asked before but I'm thinking of upgrading my lights to LED's but really have no clue how many, how big, any advice would help thanks. Tank is a 150gal and i want to grow coral (SPS) better
Thank you for the info I think I will check out some LED only tanks first before i make the change, I am a diy'er my self so i think i would prolly go that route
