    algaecide made water cloudy and created foam

    I am closing my pool today. After lowering the water a few inches below the skimmers, I added a quart of HTH Super Algae Guard 60 (polyquat 60) and let it circulate a few hours. The water is now cloudy enough that I can't see the remaining leaves on the bottom (I'm fairly sure there are a few...

    Nitrates

    I've had my saltwater chlorine generator set on maximum, but zero chlorine in the water. Leslie's tested my water and found nitrates, at a level of 50 (presumably parts per million). The Leslie's manager said there are only two solutions: add large amounts of chlorine, maybe as much as 200...

    Should I give up on salt?

    I switched to a CircuPool salt-water chlorine generator three years ago. When it was very new, the electronic portion failed and was replaced for free under warranty. Now the cell (the part with the metal plates) needs to be replaced; under the limited warranty, it would cost me $213 to replace...

    using 4-HP spa pump for pool temporarily

    My 1.5 HP pump motor died and I ordered a new (variable speed) one, which won't arrive until Tuesday. I have a spare 4 HP motor from a hot tub. If I can connect that motor to the wet end of my old pump and use it for the next few days, will it do any harm? I assume the water would move through...

    getting sand in pool, but laterals are fine

    Sand is coming into my pool through the returns, so I opened up the filter and removed the sand. The laterals and vertical standpipe are fine; no damage at all. I also opened up the multiport valve and didn't see anything wrong with it either. Now what? Does anyone have an idea what else could...

    how to take apart multiport valve with no screws

    Sand is blowing back into my pool through the returns, so I want to take apart the multiport valve to check it. My valve is made by VRAC and has no screws. It looks like maybe the upper plastic part screws onto the lower part. The top part has notches around the perimeter. It looks like maybe...

    Total alkalinity test turns blue, not green

    Total alkalinity in my spa was quite low, so I added Alkalinity Up. Now when I test for alkalinity (using brand-new test solutions), the water in the tube turns light blue rather than green when I add the second solution. When I add the third solution drop by drop, eventually the water turns...

    measuring salt level

    I installed a salt water chlorine generator last week. I measured the salt content of my pool water before adding any salt, using newly purchased salt test strips (with an expiration date on the container of 9/2016). The manual for my generator said to add 450 pounds of salt. I added 440...

    water not reaching chlorine generator

    I just installed a salt water chlorine generator. When I turn the pump on, water seems to be flowing normally; water comes out of the returns in the pool forcefully. But water does not flow into the generator cell, which is mounted (following the manufacturer's instructions) 6 inches above the...
