I’m a new member Hello everyone! My name is Brandon I need help I own a 13.5 gallon evo tank. Over the last weeks I have seen some of my corals shrink. Such as my Toadstone coral, and my polythoa and bubble tip aneome. I have had my tank for 2 years. I have two wave makers and I have the kessil a80
Light that is on a scheduled Routine. I did a water change 6 days ago I took 2 gallons out and added 2 cups of Red Sea coral pro salt and topped it off with R/O DI Water. It is Now Wednesday and no change in the corals.
MY LEVELS When Tested
-PH: 7.8
-Calcium: 480
-Salinity: 1.025
-Ammonia: 0.00
-Nitrite: 0.00 No2
-Nitrate: 10.00 (PPM)
-Temperature 80 degrees
-magnesium: 1240 (PPM)
-Alkalinity: 9.9 (DKH)

I’m looking for some advice! I have other corals in my tank such as zoas GSP that are thriving but these corals won’t open There are no fish or invertebrates that can harm the corals.

Welcome, Brandon. Let's try to get you some help.

Water parameters all look pretty good to me. I always ask if salinity is being tested by a calibrated refractometer.

Did you mix the salt in the tank? If so, that isn't a good idea.
