Testing CYA

[clayw1963]

Thanks for the help. Yes, I did clean the filter about a week after I added, so I may have washed some of it away (still in the habit from the baquacil). Did a retest this morning, waist high outside in the daylight and it is still testing low. Water temp is in the 80's (I'm in Nashville are too DavidD). I will take a sample to the pool store just to double check myself. I probably washed a lot of it away!

I have the same problem. Here was the thread that I started:

I still don't show the level CYA that I think my pool has in it. But, I just watched how much chlorine was being burned up by the sun and let that tell me if my CYA was having an effect. I went from using 1.42 gallons (1 jug) of 6% clorox to only using 1/3 of a jug in about 10 days. Since adding the CYA Going on 2 1/2 weeks now, I've yet to backwash. So, I think I've got some stabilizer in there now, but my test doesn't show what I think it should. I should probably take a sample to the store, but I think me and my pool are in sync with one another so I'm happy with what I'm seeing.
