Yippee, got my tf100 test kit. While I was waiting I did a drain and fill and my cya test is 50-55. Having so much fun, I did it multiple times. Im following the calculator with a min of 4 and target of 6 and riding the wave of success. I was surprised my standard OTO test is usually 1.5 lower than the FAS/DPD test results. I guess that kept me out of trouble with my high CYA because my TC was higher than I thought.
Now on to my CH. Leslie's said it was 600, I did the drain and fill, my tap water CH tests at 250, but when I do the CH test with pool water it turns purple. I've done the fading end point test changes without luck either. More tests tomorrow TA for one. Thanks for everyone's encouragement! Jim
