Over the last month my hammer coral and torch coral have been somewhat closed up. Prior to this they have been in the tank for about a month and half and seemed to be thriving. I have zoas and mushroom corals in the tank right now that are happy. Some background on the tank, it is a 55 gallon that has been running since july. I did a water change last weekend and plan to do another this weekend. I seem to have a decent amount of algae in the tank recently. My current parameters are
Ammonia 0
Nitrites 0
Nitrates less than 5
Phosphates 0
PH 8.2
Temperature 78 degrees F
Salinity 1.025
The hammer seems to be a little less closed up since the last water change but I didn't know if the algae was affecting the corals or what it is at this point. I also have a decent amount of coraline growing if that effects anything. I have tried adjusting flow as well and nothing has seemed to make them happy. I have attached a few photos.
