HELP! FC-O/0 Ph.8.4 TA40 Hardness100 CYA 30-40 . I have shocked the pool a few times (Which cleared the algae) and added baking soda. My pool guy told me, oh dont worry about the CYA . Is that true? My ph went up and TA dropped and no matter how much chlorine I add it still reads 0. I am on a tight budget this year and this is getting expensive. I am about to order chems online and planning to go back to Bromine just because it seemed more manageable when I used it 3years ago and about 8 years before that. We have had lots a rain as well which could be adding to this problem? My test kit is just the strips from HTH.
