I have recently had some ridiculous test results.
I am not one that cannot follow directions. I know that I am doing the tests correctly (with corrective council from this site)
I recently ran out of DPD powder and got some new. Don't know if that is relevant but I had no problems before that.
Started getting cloudy water (perhaps due to laziness in not brushing and vacuuming) and I started getting impossible FC readings (increasing FC without adding any)
Started shocking day before yesterday (and brushing and vacuuming) and OCLT was been less than 1
Pool still cloudy.
Last night OCLT was 0.
Is that possible or am I still getting screwy readings
