I'm not sure if I'm worse on this computer or the BBB. We are new at the BBB after recently spending $350 at the pool store and had 0 results. Thanks to your help, we learned to lower our cya...which we did to about 60. The last 4 weeks though we have been cleaning out the Wal Mart and Target shelves of bleach. We can not raise our chlorine level above 1 and it shortly goes to nothing. I also don't understand shocking and I have been to the pool school.....maybe I am a slow learner?
Our cya is back up to 100...from 60
chl less than .5
The pool calculator says to empty 40% of our pool. We eliminated probaly 20 " on our 25,000 gallon pool 4 or 5 weeks ago. The more I read.....the CYA should not be going up on it's own. Can anybody help? I fear emptying 1/2 the pool and 4 weeks from now we are back up to 100. We claened our filter several weeks ago. This has been a struggle all year from mid May on. Thanks for your help!!!
