I have a 40 gallon breeder with a 20 gallon sump. I have 250w MH lighting which should be enough for LPS. Amonia 0, Nitrite 0 , Nitrate is on the lowest scale on the chart I forgot what is was. My calcium is kinda high, its about 450 right now i'm just trying to figure out the dosing schedule.
The tissue is receding from three corners of one of the polyps.
