PH swing

[uhgster1]

my ATO was accidentally left off for a few hours and turned back on (w/kalk).My PH went from 8.0 to 8.6. Is this something to immediately fix or will my coral be ok? I used a Salifert test.

I think you'll be OK, but the link below might help.

You should be ok. That's not to bad of a swing. Just keep an eye on everything

Fortunately, the pH swing due to Kalk is short lived. It will correct itself before you could take a reasonable action.
