(1) I use the Taylor K-2006 test kit

(2) I use Clearview Mineral Magnet (by OREQ) sequestering agent.
(Note: At the beginning of the season (over the course of a week) I used three bottles of Natural Chemistry Metal Free and it did not get my pool to turn blue. I am not sure whether I had so much metal in my water, because I added so much fill water when I opened the pool, that it didn't reach the tipping point with the Natural Chemistry MF or whether the Natural Chemistry isn't effective. Anyway I switched to the Clearview Mineral Magnet and the pool turned blue in a couple of days.)


(3) Haven t had a chance to do the white bucket test


My pool has remained blue over the last six or seven weeks, but I haven't had to add any fill water (lots of rain)

My CuLator pack floated in the skimmer for about five weeks - and then sank to the bottom of the skimmer basket
