Thanks for the reply. I had to drain about 10000 gal out because I had been pool stored(triclor and diclor). My cya was over a hundred and I had algea I could not get rid of. Since I have been on the BBB method all I do is add 1 jug of bleach a night and brush once a week. I did add 320 lbs of salt. I purchased some salt strips and tested. Took my salt to 1650 ppm. This really seems to help the comfort factor. My pool is the cleanest it has ever been, and upkeep has been very easy.
