pH is okay.
Ammonia, nitrite, nitrate are okay.
Ca okay.
Salinity okay, but how are you measuring it? With a swing arm plastic thing or a refractometer? Could be your salinity might be out by a bit or by a lot.
Alk and KH are the same thing. KH of 5.8 is low. Should be between 8 and 11 dKH.
What's your Mg? Should be between 1280 and 1350 ppm.
How often do you test and adjust your water chemistry?
How's your water flow? High, low, medium, or a mix depending on location in the tank? Are your corals placed in the right flow areas of the tank?
What kind of lighting? When was the last time you changed bulbs/tubes?
Using RO or tap water?
