Alkalinity swing ok?

[painter1982]

I dose All for Reef daily in the morning when the lights turn on. My 60g uses 49ml per day to maintain dkh of 9.0 at 6pm when I test. Today I decided to test before the dose. Dkh was 8.4 at 9am at 6pm it’s 9.0. Is this swing ok for sps?

My system swings 1.6 twice daily.

I'm in the camp that if it's kept available it's fine.
