Hi...I just checked my small above ground pool with a test strip and it seems my water is completely off. Results are FCl 10 - ALK 40 - Bromine 20 AND pH it was yellow. the water is visibly not as clean as it was in the beginning of the summer and my little one developed a rash on her skin, therefore, I need to clean my water before she can go back it. How can I fix all those issues?
