    Pool Light Conduit Sealing

    Just replaced one of my pool lights (color logic) and to say it was a bear is an understatement. The lights were installed when the pool was refurbished 6 years ago and the installer shoved some type of sealant, which turned rock hard, about a inch into the conduit. My question is do I really...

    Subscription Renewal Not Recognized

    It seems every renewal, pool math doesn’t update my subscription renewal. Payment for the next year was charged by Apple on 11/2/22. The app showed my expiration on 11/15/22. I’m now locked out. Why does this continue to happen…very frustrating.

    Evaporation Effect on Chemicals/Test Results

    Weather forecast is showing no rain for next 10 days. What are the effects of evaporation on pool chemicals if no rain and no fill water is added. I believe, for example, that the salt ppm would be higher. But what about all the rest i.e, chlorine, ph, alkalinity, cya and calcium hardness?

    Efflorescence Longevity

    Since the pool was resurfaced, I’ve been dealing with efflorescence on the glass tiles under the spillway. I’m in the pool often so the constant cleaning hasn’t been too bothersome. Lately, the efflorescence seems to be less than in the past, maybe it’s wishful thinking, but I was wondering if...

    Heater Woes

    Installed a Hayward H250IDPL2 in January 2007 and has worked flawlessly until today. Living in SW Florida it is not used excessively so every couple of weeks I fire it up and let it run for 5 or 10 minutes. This morning I fired it up, it ignited and then shut down. It tried to restart, could...
