The LFS has a 3" super colored corcea. Absolutely stunning blue. I am really interested in it for $65 but it would be my first clam. If I do get it, it would be going in my 29g about 4-5 inches below the water surface 10" from a 150w metal halide. Would this be enough lighting? My CA levels run 430-520. My Alk runs 9-12. I do not dose, and maintain my levels via water changes. Although am not completely against dosing in the future but my demand does not call for it.
