I just opened my pool 12 days ago. After correcting what the pool store called a chlorine lock problem (TC 8ppm FC 0) I now have an issue with my water not holding FC level. Over the past four days Iíve added 16 gallons of chlorine (12.5%) along with 12 bags of regular shock and my TC & FC levels have not changed still 0 & 0. The pool water is relatively clear but not sparkling. At that point I went to the internet and began searching for answers. Thatís when I came across this forum. The following are my latest test results from my pool store.
FC-.5ppm; TC-.5ppm; CC-0ppm; pH-7.5; Hardness-140ppm; Alkalinity-130ppm; Cyanuric Acid-4ppm; Copper-0ppm; Iron-0ppm; Borate-3ppm.
Their recommendation; 13#s Calcium Hardness, 5#s Stabilizer & 3 bags of Shock.
