I have ditched the trichor tabs because I found out they were the "dual action" w/ the copper. Hopefully I got them out before my pool became too polluted with copper. Green cast to the water this morning, but by afternoon it has cleared up for the most part.

Still trying to figure out the home HTH kit. First test I did showed pH around 7.0 range and chlorine was inaccurate because I shocked the pool with 3lbs of cal hypo again this morning. I did get another pool store test reading (somewhat limited because their printer was down).

CL - 1.5
PH - 7.2
TA - 145
CH - 182

The CYA isn't showing up on the test yet, since I just put stabilizer in the filter last night.

Pool store doesn't like that I'm using the cal hypo to shock and chlorinate because of "inert materials that will clog up the sand filter".
