Hello,
My tank pH apparently dropped suddenly from 8.46 to 8.02 from one reading to the next maybe 20 minutes (see screenshot below)
Tank has been set up 2 years this month (125 with large sump and decent skimmer)
Has 5 fish (clown pair, dottyback, puffer, velvet damsel)
Mushrooms, toadstool, a couple other small corals
Everyone looks perfectly happy (haven't seen the brittle star as per usual)
SG: 1.026
Alk: 10 ish
Nitrate and Nitrate: both 0
ATO water has plenty of buffer and I had added water 2 days before this happened. It was topping off normally maybe every 2 hours and pH was going up as expected.
I was out of town and didn't add anything to cause this
Has anyone seen this before
