All,
New member and would appreciate any help. A few weeks ago, we thought we had metal stains and tried to get them out. using local pool store advise, we let chlorine drop to zero and used the metal free etc with associated backwashing etc. Since then we have not been able to get the chlorine levels back up. We have dumped in whole lot of Chlorine over this time, raised the PH which had dropped etc. The current readings are
Free Available Chlorine -0, Total Available Chlorine - 0, pH - 7.4, Total Alkanity 120, cyanuric acid 100, calcium hardness - 140, phosphate - 0, nitrates 5 ppm. A week ago, TC was 2, FC was 0.5 and we had 6.8pH. We live in North East and are running out of ideas. Inground 32000 gallon pool. Pool is clear and looks swimmable. Brown stains still there.....
