Unable to keep chlorine level and CYA level has dropped from 38 to 21 in 1 day.

Great example of why we don't trust pool store testing, by the way. (I couldn't resist posting a table of the results you reported!)

I did buy a little kit until my big one comes, my CYA is now 50. I added something called Questout ? to remove all medals from the water. The pool looks great no algea it's clear and blue just NO CHLORINE LEVEL Free & Total CL is 0.

Ben/ Lisa:: 5 days ago (along with the previous 4-5 weeks) my CYA level was an "uncomfortable" 65... Just took the test again (with the 2006) and the levels are -ZERO- (( Within those past 4-5 days, I've dosed PolyQuat and started the Ascorbic treatment )) Im sure you recognize my user name and know what I've been going through the past few months..... Something ate that CYA in the past 5 days.... I thought it may be the reagent itself, but it came from the same bottle that I tested with last week....
((So much for enjoyng the pool WaterMom ))
