    Pentair IC20 Premature Failure – Questions

    A few weeks ago the "Cell" light on my IC20 began to blink slowly, and the diagnostics screen on the EasyTouch says "Clean Cell!!!". Pulled the cell, and saw no visible calcium scaling, but went ahead and added diluted acid as instructed, and saw no fizzing. So, it seems that the cell has...

    Door Alarm Question

    So, I understand that most pool door alarms have a 7 second delay before the siren sounds, with a bypass button that cancels the alarm. But does anyone know of a door alarm that will BEEP during this delay period (as a reminder to push the bypass button)?

    New building code for low voltage lights around pool?

    I've been reading with great interest the various posts here and elsewhere regarding low voltage lights, and how they are not allowed to be closer than 10ft. from the water's edge. Some people say that it's dangerous, others say that with a pool-specific transformer it's perfectly safe (though...

    Fiberglass owners... does your pool have any gelcoat cracks?

    Our in-progress fiberglass pool was not set level and as a result has so many gelcoat cracks that I can't even count them all (I've tried). Here's the thread with all the gory details: new-fiberglass-pool-is-full-of-cracks-help-t43101.html We are in the process of sending a formal letter to...

    Is it reasonable to expect zero algae?

    The water is crystal clear, but very 3-4 days recently I'm noticing a light accumulation of what appears to be greenish algae on the walls of the pool, which is easily "dusted" off with the brush. I had been testing with strips (which led me to believe my FC level was about 4), but the TF100...

    Easiest way to clean small & shallow pool (similar to a spa)

    Our fiberglass pool (if it ever gets completed) has a small (about 6'x6', 6" deep) attached "tanning ledge" (we call it the baby pool): The main pool will eventually have a Polaris pressure-side cleaner, but in the meantime I've been manually vacuuming it periodically, at which time I also...

    New fiberglass pool is full of cracks... HELP!

    I'm feeling really sick about this. Our pool is almost done (a few odds and ends need to be taken care of, and deck is supposed to be poured next week), and my kids are just dying to be able to go swimming. Even though it's still under construction, I've been trying to keep the water clear /...

    IC20 + two speed pump = low flow error

    Greetings all. Our pool is nearing completion, but a problem has surfaced. When the pump (a 1hp Superflo two-speed) is operating on low speed, it's hit or miss as to whether or not the IC20 will function. Sometimes it works, but often the Easytouch panel (as well as the red light on the cell)...
