Monti looks bad!

Preview
My monti looks pretty bad. When it usually starts to look like this. I do a water change and its back. Full red, with blue polyps. Last two days after the water change and nothing has happened.

DKH = 11
CA = 420
MG = 1400
PH = 8
Salinity = 35

What might be going on? The light is an AI Prime about 30-35%, 8 inches off the water.

What about ammonia, nitrite, nitrate, and phosphate? Do you use rodi water for your top off and water changes? Any dosing?

If nutrients are low then I wouldn't keep my alk that high. if nutrients are high it might be unhappy as well. Water changes should be lowering NO3, phos so i'd probably test and see where you are at with those

My test kit is an API so they look to be zero or close to it. I fudged up and got "Coral Pro Salt" when I was setting up this tank. This tank has been a pretty consistent with 12 dkh for the past 7 months. 11 is actually low with they they are use to.

Coral pro salt is great to use but I would do smaller water changes since the alk mixes a bit high. I'd let the alk come done naturally, try feeding a bit more too. I don't think you have zero nutrients even if the api kit says so but running that salt does require some nutrients with your current alk reading.
