Hammer & Frogspawn coral question
I've had these in my tank for a good 11 months and they don't seem to grow at all. Should I be adding some sort of suppliment in order for the skeletons to grow?
Right now I just use high quality Salt /RODI water and purpleup. This is pretty much all I do. Calcium levels range from 420-450
Any suggestions would be appreciated.
