I know everyone has experience this at least once and I am sure there are lots of other threads that provide recommendation on the same topic but I was lazy and decided to post a new thread.

I have two RSM 35g tanks. One tank is to fantastic and all my coral are growing and do outstanding. My other tank is doing good but a couple of my corals are not opening. I am guessing there is something they do not like. I have check the Calcium and Alkalinity and both are fine. The temperature is 78 degrees and salinity is perfect. The lights are only a few months old. My only guess is the stability of the chemistry. The good tank has an auto-dosing pump on it for both Calcium and Alkalinity. The other tank I do manually. I also add iodine and Magnesium to both tanks.

Any ideas
