    It'd be great if they were actually open when they say they're open. Just tried getting a water sample tested before their posted closing time on 5/18. Arrived 20-25 minutes before closing time and doors were already locked and lights off. No notice posted - phone nessage, Google, and all normal locations to see hours stated they were open until 6pm.

    So frustrated. I have a new inflatable hot tub, and I've had two frustrating experiences with Leslie's. The first time I went in (the good time and owner of the 2nd star), I was told to just get shock, that I didn't need chlorine or bromine. But if course, I had read the booklet, so I had to do it my way . . . LOL! Ended up getting bromine. After adding it and reading more, I realized I did need shock, so I went back, explained my situation, and a different clerk gave me the shock. Got home, and it was chlorine shock (even though I told him I had bromine treatment). Luckily, the first clerk had told me not to mix the two, so I had to take it back. Today I went in for chemicals for the pH and TA. He gave me two of them. I said I was expecting three, two for raising and lowering pH and one for TA. He just kind of stared at me. I asked if this would do everything I needed it to do, and he said yes. Got home, and my pH is low. I need to raise it, and neither of the things he gave me will do that. Called the store and was told they don't have anything to raise the pH right now (may not have been the same person). I said that I was told I wouldn't need anything else, and he said yes I did, but they don't have any right now. Over Leslie's!
