    Secondary systems for health concerns...

    "Our understanding is that chlorine disinfection byproducts are associated with a ton of issues, including higher incidence of cancer." Aren't those concerns about drinking chlorinated water?

    Pool Replastered in February 2025

    If I did a plaster job, the result would probably look similar. But I had never done it before.

    Conventional Wisdom re SWCG plumbing placement

    It's a good point about CYA - the water leaving SWCG is probably much more aggressive (oxidizing) than what the target FC and the CYA level would suggest.

    Conventional Wisdom re SWCG plumbing placement

    What's the chlorine contents right after SWCG when the target is set to 7 or 8 ? Is it close to the target or rather much higher, something like 15?

    Replacing pump with Calimar VS

    With a booster pump and Polaris cleaner there is no reason to run VSP at a higher speed during cleaning intervals. When selecting the minimum VSP speed just make sure that your SWCG's flow switch is satisfied and the skimmers are still effective in collecting debris from the pool surface.

    Frozen Water in Vinyl Liner pool, worried with storm coming

    A mesh cover may get destroyed by the weight of snow if the water level is too low. This is the reason why I don't lower the water in my pool below the returns; instead, I blow the returns out with an air blower and plug them. The minimum water level for my mesh cover is 18 inches below the...

    What's one thing about pool maintenance that most people don't realize, but really should?

    Yeah, the subscription fees would be too much for me, and software should be free. I spend all my allowance on hardware.

    Hayward Aqua trol RJ (by pass salt reading)?

    I would look into confirming that your digital tester is correct. Get the Taylor's K-1766 drop test. It's currently available on Amazon at $31.

    Swimming season is coming to an abrupt end this year

    I ordered for my A&S pool several dozens of various sizes plugs on Amazon a couple of years ago. Didn't notice any quality problems. One of the two skimmers has a connection to the drain, so that one needs a combo of two plugs separated by a spacer; another spacer is between the upper plug and...

    Mesh cover recommendations for inground pool 36x16 (DIY install)

    We have a free-form RuggedMesh Meyco cover, bought in 2017 as a replacement for a 10-years old non-rugged mesh, also from Meyco. The RuggedMesh acts as a filter for dust/debris, which dries up on top of the cover and can be easily blown off. We open the pool to a much cleaner water than with a...
