I'll never set foot in a Leslie's again. They are there to sell you chemicals and to boost their bottom line. That's it. Their staff, while friendly for the most part, is incompetent. They test your water, but I don't believe they do that accurately either. I've spent hundreds of dollars on chemicals this summer to "fix" my pool, as I was told on numerous occasions it was too hot to drain my pebble tech pool. After trying their BioActive product (which is a farce and doesn't work), as well as buying other things such as Phos Free, shock, and everything else you can think of, my pool turned green. Well, I gave up, hired a pool guy last week who advised differently. He drained my pool, washed it, and we are swimming less than a week later. I wasted half my summer not swimming because I listened to Leslie's. Never again.
