Hi ,my daughter just bought a house with an above ground pool with swg and hayward sand filter and floxl .we just uncovered it last weekend and the water was crystal clear but the pump was broken so we ordered a new pump and my husband just installed it last night and got it up and running ,but the pool turned swamp green over the last few days . we put 2 bags of salt and a bottle of shock ,they are going to add more this morning . there were tons of tadpoles which they tried to save as many as possible and pine needles but we got most of those out and they have been dumoing the skimmer every couple of hours . can anyone tell us what to do or does the filter just neecd to keep running until it clears up .?? Thanks for any advice
