I recently decided to switch salts from aqua vitros salinity to red seas coral pro salt mix. Red Sea has higher levels of Ca
, and Mg
. which is supposed to accel growth. Being that I was looking to accel growth on alot of frags I thought it was a good move. I was wrong I think I might have changed to much to fast. I started water changes 3 days ago changing 5 gallons a day. Except yesterday I did 10 gallons. About 2 hours later many of my sps
started retracting the polyps and fading. This morning almost every coral has lost significant color and retracted polyps. Not sure if I brought levels up to fast with water changes or what? Any suggestions would help.
