I rescued my pool at the beginning of the year from an algae bloom that occurred right before closing, using the SLAM method. I have been using the TFP liquid chlorine method(10% HTH liquid chlorine) of maintaining my pool all summer. The sand in my filter is 2 years old. My water has been clear, but not crystal clear all summer, but I have needed to vacuum algae and/or debris off the bottom almost every day. I have SLAMed the pool twice. The first time removed the algae growth for about a week or two. This time I have algae re-growing overnight at chlorine levels of 16 PPM - 19 PPM with no FC loss overnight. I've been reading all of the Algae articles, and I'm baffled. Do I have regular algae, mustard algae, pollen???
