My tank is mostly a softy tank with a couple SPS frags.
Since switching to AWC and then changing salts, I have had unexpected dKH measurements.
Before AWC, I was doing monthly 15% water changes....and my dKH would stay between 7.5 and 9.
After switching to incremental 3% daily AWC, dKH kept climbing to as high as 10-11dKH. Since I was transitioning to Triton Method, I was targeting 8dKH and quickly realized my IO reef salt was the issue. Then I switched salts to Neomarine, but have had unexpected higher dKH and find it difficult to get to 8dKH and use my Triton 7 dosing.
The tank has never looked better, but I am having issues with Yumas and Ricordea. Nems are doing great, zoas seem happy, other mushrooms are happy...just not Ricordea or Yumas.
For a couple of SPS frags you dont need to use triton dosing ( or any dosing) as there will be very little Alk or ca usage. Your auto water changes should be more than sufficient for whats being consumed.
