Hopefully I don't lose much either. !I butt dialed a liter of ALK once. Hit about 18dkh and the only thing I lost was a blasto. All my SPS survived. No PE for a while but WC was all I did to correct.
Update: 2nd emergency WC finished. Looking much better. All my rocks are white but I'll worry about scrubbing those later.
Alk is 9.5 after the WCs. Ph still 8.2. I usually keep my tank 8 to 8.5.
Will prepare some more water and perform some smaller water changes this weekend.
Again, eternally grateful for the urgent help to all of you.
Thanks. Good to know. Will wait to scrub them then.Honestly, Alk @ 9.5 is fine - just let it drop - may rise a bit though if you scrub / wave the white stuff off the rocks as that's also Alk that hasn't mixed with the water properly
