I have had a frogspawn for about 6 months now but haven't seen any real growth in it. My Polyanthids, zooanthids, kenya tree and xenia have all expanded but not the frogspawn. Should I be dosing the tank? I don't have a reef test kit to see what calcium and stuff is, buts its only one head. I didn't think it would take enough from the water to matter, but maybe I'm wrong... Thoughts?
