    algaecide made water cloudy and created foam

    Wow, that is sneaky! I saw the dimethyl part and thought this was the good stuff. I will know better next year!

    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'm about to order a new test kit. On the Taylor website, it says the FAS/DPD test can measure chlorine up to 20, while the PoolMath chart says I need to bring mine to 31 to SLAM it. The TF website doesn't mention this limitation. But aren't they both selling the same test using the same...

    Nitrates

    I am catching on to all this. Thanks for the helpful advice. I found 10% liquid chlorine at a great price (store going out of business), and will brush the pool and pump out water to lower CYA tomorrow. I've never had this problem before, and I'm wondering how much liquid chlorine I should buy...

    Nitrates

    The water looks OK except for a bit of algae in some spots.

    Nitrates

    Where can I buy liquid chlorine (Home Depot and Walmart don't have it in my area), and how do I know how much to use? It seems that the advice here is the same as one of the options mentioned by Leslie's -- add lots of chlorine -- except that it's a different form of chlorine.

    Nitrates

    High CYA seems odd because I haven't added any in a while, and often need to add some. - - - Updated - - - I could add chlorine manually, but it seems like I shouldn't need to do that. That's what I bought the salt system for.

    Nitrates

    I recently had the cell replaced under warranty. Of course I have my own test results -- except for nitrates, which I don't have a test for. I just re-tested and found .5 free chlorine, 1 total chlorine, pH off the charts high (had to add two quarts of muriatic acid), total alkalinity at 120...

    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?

    What is your salt level? When I bought the salt system, the promotional material said it would display the salt level, but my system does not.

    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

    Good questions. I have had Zeobrite in the filter for a few years and never had this problem before. The filter tank seemed to be less than 2/3 full. I can see that the Zeobrite particles are bigger than the openings in the laterals. I have not noticed what position the valve is in when the...

    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

    No screws under the label. The tube does not have a screen at the end. Could the sand be getting back into the pool through that tube? It seems unlikely, as that tube has been that way since i installed this filter one or two years ago, and I never had the sane problem until now. (Also, the...

    how to take apart multiport valve with no screws

    There is a small plastic tube next to the vertical standpipe. What does this do, and should it be connected to anything?

    how to take apart multiport valve with no screws

    There is no name on the filter body itself, just VRAC on the multiport valve, along with Code 22358 and Serial Number 07318-3260. Googling has not turned up anything useful yet. - - - Updated - - - And now I'm wondering if I should even bother taking apart the multiport valve, or just bite...

    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

    Thank you, gentlemen. What you say sounds logical, as the bromine level in my spa is very high right now.

    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...

    Do you need Phosphate Remover?

    Re: doubleOkevin Personally, I found this thread (which I read completely) totally confusing and unhelpful. One side insists that phosphate levels are crucial, and one says to ignore them. I don't know who to believe.

    measuring salt level

    I've been using pucks ever since I got my first pool in 1993, so they are familiar to me; I thought the salt water generator would be simpler and cheaper. If I can get everything working correctly, I still hope that will be the case. My Circupool SJ-30 generator doesn't display the salt level...

    measuring salt level

    My initial salt level was 500 ppm -- again, according to the seemingly unreliable test strips. I will get the Taylor kit and give up on the strips. I anticipate pumping water out and adding plain water to dilute the salt level. If I had to live with the current saltiness, I think I would...

    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

    Duh! Now that you explain it, Dave, it's obvious. I used Tees instead of 90 degree elbows, so the water is of course bypassing the cell. Believe it or not, I renovate houses and do a lot of my own plumbing, but somehow I screwed this up. As for the plumbing: the cell is the last thing. The...

    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...
