Hanna ph checker off or is my ph just high high

Reefing.with.Rich · Feb 17, 2023

My Hanna ph checker is now flashing at 8.6 which is meaning the ph is higher than 8.6 so should I just go with the flow or should I figure out how to bring my ph down some?
I don’t dose anything right now
Just auto water changes daily(7L)

I wonder if your reagent is bad. I’d check the ph with another test kit before starting to dose anything. Good luck!

It’s the same reagent iv been using for weeks now
Days ago things were normal and then I left the windows open one day and noticed it went up quite a bit but hasn’t came back down for two days now

I had the same problem and the checker actually went bad as determined by Hanna. It’s very hard to get to or actually be above 8.6 in pH. Verify your reagent is still good, ( I had a new bottle with the same problem on the checker occurring) and if it continues contact Hanna. They will have you send it in and if it is bad they returned a brand new one back to me. (I was within a year for warranty). Good luck

I have a spare bottle of reagent so I’ll try that, and then I’ll try my salifert ph test kit and then go from there
Thanks!!
