Super High Alkalinity

[mrow1997]

Hey everyone,
I have a 90 somewhat mixed reef and I have been dealing with increasingly high alkalinity over the past few months.
Today it’s 15.3 according to my salifert test. It has always been high without issue, but never to this extent.
I’m not having too many issues with corals. My growth however is definitely not where it used to be.
My chief concern is fish loss, I’ve lost 3 fish in a month. 2 lyretail anthias and a flame hawk fish. No signs of disease. No signs of malnutrition (fed 3 times daily on auto feed with frozen at night).
Other values: Ca: 480, Mg 1290, Nitrate 10, Ammonia 0, PH 8.24

Main question is how do I go about correcting this.
I currently dose all for reef and use tropic Marin pro reef salt.
Im assuming the answer is that it’s likely time to transition to dosing 2 part or something similar.
Lmk your thoughts.

Try testing with another test kit, I know it’s a pain, but it’ll help to double check your numbers and if the numbers are relatively close than devise a plan of attack.

I’ll likely bring it to the store to have it tested to double check. Thank you!
