Boomer, my PH has been creeping up over 8.4 all week during the 6 hour MH photo period. Today when I got home it was 8.55. so I added some vineager to bring it down.
What would you recommend? Thanks Jim

More than likely algae is growing on he probe and needs to be cleaned.

Ya know it looked pretty clean Boomer.

Almost any time you see a pH like yours in a reef tank it is a testing error 99 % of the time, unless you are dripping in to much kalk or adding to much buffer. It is usually a dirty probe or a probe that needs to be recalibrated.

I'll try recalibrating. Thanks Booomer!
