I've heard people say that clams don't do so well under LEDs. I've been thinking about getting a small clam but if what they say is true, then I'm not going to. What are you guys' thoughts on this? Does anyone currently have a clam under their LEDs? I have 2 120w led fixtures over my 70gal. Have been growing LPS and SPS very well, and have a RBTA that just keeps growing and looking great.
