This is my third year as a pool owner, I have never had an issue with any cloudiness or chemical balancing issues until now. I am at a loss for what to do now so hopefully someone can give some idea of what is going on.
The pool is an 38,000 inground vinyl liner. I opened the pool a week ago and it was cloudy. The initial water test said there 0.5 ppm TAC and 0.5 ppm FAC and my copper levels were elevated to 1.6 ppm. Last year when I closed the pool my CYA levels were at 100 ppm, but after opening and the initial test it was now only 29 ppm. All others (Ph, Calcium Hardness, Total Alkalinity, phosphates, iron, TDS) were fine and in their normal ranges. I shocked the pool with 80 oz. calcium hypo 73% waited 4 hours and read the the test showing 3.0 ppm TAC and 3.0 FAC. I then ran Natural Chemistry metal free to try and reduce the copper in the water. The next morning I tested the water and showed absolutely zero chlorine. No TAC no FAC. So I shocked again 80. oz of calcium hypo 73% and waited about 8 hours took it to the pool store and tested it there. The store test showed 3.10 TAC and 2.6 FAC, and that the IRON was coming down and was now at 0.8 ppm. All other chemistry was completely fine (TA 100, pH 7.4, Calcium Hardness 280ppm, CYA 30ppm). Went home and tested with home kit and it showed the exact same as the store, 3.0 TAC and 3.0 FAC. Tested it the next morning and once again 0.0 TAC and 0.0 FAC. So I figured ill show you.... Dang pool. This time I dropped 10 pounds of shock calcium hypo 73% and 2 pound of di-chlor. Waited 4 hours and it showed TAC and FAC at both 10 PPM. Then tested again another 4 hours later and it had already come down to TAC and FAC at 5.0 ppm. The next morning 0.0 TAC and FAC again. Took it to the store and they had same result showing 0.2 TAC and 0.1 FAC and all other chemistry is fine. What is going ON????????? I have read that there could be a large amount of Chloramines and that can prevent super chlorination unless you do 10 times the difference between TAC and FAC. But they both keep showing the same. Has anyone else had this happen to them? If anyone has any insight it would be much appreciated because now I am getting really frustrated.
