My kit is a mix right now. Started with HTH 6 and have added FAS/DPD and CYA test from tftestkits.net

I am still passing the over night test and still have no cc or .5. Never over.

My cya is accurate as I have had myself, my husband and my daughter all run the test. 35-40ish

I figured it had to be mustard algae. Nothing else made sense. Last night I dosed the pool to 24 ppm per the PoolCalc and it was still in the 20s at 3:00pm today. .

The only off thing is my PH skyrocketed above 8.2 tonight. Should I treat even though the test may not be accurate?
