40 breeder tank. So it's 18" deep. I had heard that lenses contribute to a better coral growth. My corals are doing fine. My frogspawn started out as a one headed frag five months ago and now has three heads. Same with other corals. I just started adding SPS
corals and was thinking of a way to improve growth. All of SPS
are doing great. Red Monti Cap is doing the best. Technically I don't need lenses based on growth I have. Just trying to find for ways to improve.
