New to this. We did the abscorbic acid treatment about 2 weeks ago. All stains were gone and started rebalancing the chemicals - slowly as was told. Then the stains started resurfacing just like before. Went to the pool store and was getting some sequestrant and they told us to add the Metal stain remover - Metal Free - instead! Didn't work so two days later we added more AA NOW THE POOL IS CLOUDY! What do we do?
