Hello all. I have just had an above ground pool with SWG installed a month ago. It holds 34000L of water.(I'm in Canada). It has a vinyl liner, hayward pump, hayward sand filter and I use a solar blanket at night. The water temp is 86 F. As mentioned in the title the water is crystal clear but I cannot keep any kind of reading of free chlorine. So I did not want to do this but I went to a pool store for a test. These are the results they gave me. My salt level is 2450 and for my gen. it should be 3400(from owners manuel) but the low salt level warning is not going off. Alk is 185, Calcium is 200, Chlorine is 0.2, Stabilzer is 25 and Phosphates are 2500. So this is their suggestion. Clean the deposit off my salt cell(there is a little buildup on the contacts not the plates) to get a better salt reading, use 5 liters of muratic acid to drop Alk level and use a product Phos free to get the phosphate levels down. So with all this being said I don't know what to do? If I start screwing around my water will not be clear anymore? I have done alot of reading on the site and alot say not to trust pool stores, but I am new and did not know where to turn. My 4 year old has very sensitive skin and I want to put the least chemicals in pool as possible to help her that is why we chose to invest in the SWG. Anyone have ideas? I did purchase the products they mentioned but have not started anything yet. Even with my own test I do show a high Alk level. Any help great.
