Hi, I'm going on season three of following TFP. So far, so good, have not encountered any issues with our pool. This season, I purchased TFP's pH meter to try to ease my pH testing... I calibrated it according to instructions, but found it to be off (high) by a couple of points compared to the drop test. I then purchased a highly-rated one from Amazon (two decimal points) and after several attempts, found that it's also a bit off (low readings this time compared to the drop test).
Both instructions said to rinse with distilled water before and after use... and to dry with filter paper. Now I'm reading elsewhere in the forum that I'm supposed to keep it wet? Should I rinse with distilled water and go straight to testing without drying? And also store with cap without drying? Just trying to figure this out...
Thanks for any advice!
