New Taylor kit 2600c .3 months old. Pool was hitting all numbers since First opening except for CH...Fiberglass pool 7700 Gal. On Tue had CL 1.4 PH 7.6 ALK 70 CH 120 CYA <30. Added half of pool math recommended 72oz by weight 36oz of calcium chloride. Retested on Thur and CH was still 120. Put numbers back in pool math and realized I was using calcium chloride dihydrate round pellets from pool store(chemical not marked anywhere on jug) and needed more chemicals. Figured no big deal I only put in half last time and probably only 1/4 of what I should have put in since I was using the dihydrate .Pool math said use 137oz by weight of dihydrate on Thur. So I added about half 76oz which was the rest of 7 lb jug. Now on Friday I got FCL .4 PH 7.4 ALK 70 CH>800 CYA <30 . Kids, grandkids, pregnant girls, babies they will all be here Sunday. Can they get in water ? I also have a well and have 2 options 1 spigot is untreated and one softened water. Thanks
