Three weeks ago I refilled my pool after a restoration with Wet Edge Satin Matrix. It looks great and the water is great. I had my first swim at 72f - brrrr!
Anyhow, I bought a fresh test kit, a TF100. I wanted a fresh start.
My numbers are:
CH=400 or 240?
I am a bit low on the CYA but the guy who initially dosed the CYA said since I use some trichlor pucks in addition to bleach it out to work out. I think I need another ten points because my 24-hour test with FC has it dropping a full point. We have had bright sunny weather. It is way too soon to be consuming FC at that rate.
The CH is absurd. I went to the pool store and the kid measured 240. He was using the same taylor reagents with a 10ml sample.He had one of those fancy spinner mixers but that shouldn't make this kind of difference.
I repeated the test three times - even tested the city water. I even had my wife read the instructions and witness the procedure.
What's going on here?
