wtb PH meter


New member
Does anyone have a PH meter (good/excellent condition please) they want to sell? If you have calibrating solution (7 and 10) I would buy those as well. I want it to plug into my Reefkeeper 2.


Also, if anyone has PH 10 solution only, I have a pinpoint PH meter I never tested. I already have 7, so it's all I need as far as that goes.
