Hello,\n\nI need help, I have a 55gal reef tank with 3 leathers, kenya tree, a couple montipora and a sea fan. I have a wrasse and a chromis and plenty of snails and crabs. A couple of weeks ago I had an outbreak of red slime algae and since then my tank has not been doing well. The algae is gone but nothing is bouncing back. I have tested my water and was told that my calcium and dKH were high, I bought some tests and confirmed that they are off the charts. My salinity is 1.027, ph is 8.8. In the past my water has always been perfect. I upgraded my lights a few weeks ago to T5's, I dont know what else to do!!\n\nPlease help, how do I get my corals to grow and expand! They don't look bad but are not growing and expanding like they did at the farm when i bought them. My montipora is bleached white. \n\n\nI dont know what else to do!!
