Good Day Girls & Boys....! NewBee here that volunteers at our community pool. Jumped in with both feet so to say 90,000 gals of neglected maintenance for years has become come quite a challenge. Working to solve issues of every sort and now waiting on #20 silica sand to reload the filters and rebuild the control valves. Can't wait to see how that's been gerry-rigged Y'all make it a powerful day and I hope to get some great information here on TFP
