i love my hayward sand filter and pump. when the pump and filter that came with my pool died i began shopping around for a new one. In my ignorance I did not realize how poorly my original pump and filter worked. I was continually vacuuming and i added hundreds and hundreds of dollars worth of chemicals to my pool this year. I was adding 2-3 bags of shock every few days, along with anywhere from 10-15 chlorine tabs and 1/2 jug of algecide. Even so, my pool was never truly clean. If my kids and grandkids didn't love the pool so much i would have been tempted to just slit it open and have done with it. I was spending a fortune, working myself to death, not enjoying the pool, and growing more resentful by the day. I know it sounds cheesy but getting the hayward sand pump and filter changed my life. Now i vacuum... maybe once a week, add 4 one inch chlorine tablets every couple of days and a weekly pkg of shock, if it has been really hot or rainy i might add a cup of algecide. the water is crystal clear! now i love my pool too! Too bad it is almost time to put the pool to bed for the winter. At least i know next year i can more easily afford the chemicals, AND best of all I'll get to enjoy it not just clean it!
