Some of you may have read in one of my other posts that we bought a home with a pool and although it looks great the numbers are high from years of tab chlorine. I will be doing a partial water change to get my CYA down from 100 and will be a BBB user. I have not added any chlorine since we moved in because FC is still high at 16. I am however curious though in the meantime on your cycle of adding bleach to your pool. Are you adding a little every day or every other day or so?
