I got the Sodium Clor. test kit along with my TF100 last year, and I didn't use it all that much once I got the salt correct, it was just a once a month thing or less.
I did the test this spring (so the reagent would be about 8-10months old since I got it) and the milky colour of white for the salt test was fine, but when it turned red, I got a ton of tiny white solids particulate forming in the container. I can't for the life of me remember that happening to that extent. My reading is low - about 1800 (target 3200-3400).
Is this still normal or is perhaps the reagent old? I was hoping to go this season before replacing it all.
