Hi SeanNDenise - I make my own water at home from the city water supply with my RO/DI and 0ppm TDS.
I just started using Aquaforest Probiotic Reef salt (two water changes ago), before that I was using Red Sea Reef Pro (for two years), which would likely explain my higher Alk, I've heard it can cause the Alk swing. When I switched to AF, my Alk after a water change went gradually down to 8.1ish from 12(!).
Well it sounds good then.
I was thinking maybe chlorine or chloramines maybe but seen you haven't had any fish losses.
I use salinity too, switched from rc because of crazy high alk in 3 different buckets 13-16 was mine.
Sounds like you are doing everything correctly.
Only thing I could think of is your lights are too bright, maybe turn them down or not such a long period they are running.
Or maybe you have a bad test kit somewhere and are getting a inaccurate reading.
Or stray voltage, which is easy to find with a paper cut on the finger lol or the smart way with a voltage meter.
Other than that I'm stumped .
