Hi everyone. I had no choice but to remove my live rock and replace with some new reef rock. Phosphate was a nightmare and over two days my phosphate has dropped by 85%. I've now noticed a load of strange looking things in the aquarium not the sump can anyone point them out and tell me what these are?? I've seen about 20 of them run on the back.
