Recently bought some frags from my lfs. Got a candy cane, an acan, zoa, and hammer. Zoas have some hair alge that needs taking care of, my acans look happy, candy cane looks ok, but since I bought my hammer it hasn’t opened up great and now it’s closing. It’s a new reef tank, salinity is at 1.024-1.025 and ph is 8.0-8.2. Pics below
