Yes i want to know this too cuz i'm about to get a new mvb and i heard its the best one. Then i saw the old thread about the possible eye issues it may cause. So i'm not sure which is good now?
I consider the PowerSun to be a middle of the road bulb. There are worse (the Nat Geo bulb comes to mind) but there are much better (MegaRay and Arcadia).
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
