I hate being Color Blind - Strange Test Results

[aylad]

I still highly recommend draining and refilling about 1/2 your water before you do anything else. However, if you don't want to do that, then make SURE your chlorine stays above 8 ppm. I agree with CarlD that you're done using the pucks for this year--the low pH and high CYA are direct results of trichlor, and while you can use Borax to compensate for the low pH, you are quickly reaching a point where the high CYA levels can't be compensated for effeciently.

If you don't want to drain and are willing to keep your chlorine in the 8-10 range (I suggest using bleach to do that) then give your pool another day or so to clear up, then add small amounts of baking soda until you get your TA to around 80 to 90, then stop. As long as you compensate for the high CYA by keeping your chlorine higher, and don't let your CYA rise any more, you should be good to go for the rest of the summer!
