ph probe question

Does the ph probe need to sit stationary in a sump? I ask cuz the probe holder holes in my sump are larger than the probe and it moves around?

It is best to keep it stationary in my opinion. Air is the worst thing for it as it can effect accuracy. What you want is a gentle constant flow across the probe.

Well the probe holder is right in the return section of my sump. I have my skimmer in there and the return has a filter sock. I guess i can use the suction cup holder to keep it in place in the holder. Kinda defeats the purpose of a holder lol
