Still getting the hang of dosing All for Reef. Felt like my Alk was always a constant 7 as I ratcheted up my dosage from 10 to 25 ml/day since Dec then I got lazy about testing and killed a couple sps frags before I noticed it was 10+
Got the tank back the 8 range after a water change and a few days of patience and turned the doser back on and gonna be testing daily.
While some frags bleached and died others had a growth spurt - my Digis in particular seemed to like the higher levels. I know some people run their tanks in that range with success. Definitely a bit puzzled where I messed up ... I thought calcium formate could only slowly raise things but it makes sense you can overdose like any other supplement.
