PH probe dropping

My PH in my tank (according to the probe) has dropped from about 7.8 all the way down to 1.24 in the last week or two. Would this be a recalibrating issue or something else. I've been battling hair algae and was dosing vinegar and mag to try and combat the hair algae. Once I noticed the decline in PH I stopped dosing those but it stool keeps dropping.

Sounds like a bad probe. Clean and recalibrate it. If it does the same thing, it needs to be replaced.

Some diluted vinegar. Be gentle with a toothbrush. Dont go nuts its probably a bad probe. They last about a year.

Dosing vinegar will drop your pH in your system.
