I’m trying to recalibrate a 6mo PH probe and purchased 3 packs of 4ph, 7ph and 10ph PinPoint kits.
When calibrating the 7.0 solution, the closest I get is to Red. Last night I was messing w/recalibration for about 2hrs.
Will accepting the 7.0 in red throw off the 4&10ph calibration numbers?
My worry is dosing too much kalk from my reactor. I try to stay around 8.35
