Best $15 you can spend for your pool
We are first time pool owners at our new house. We bought it in November and couldn't have a pool inspection done due to the time of year. We had no idea what condition the water was in until we pulled off the winter cover this April. As you can see, the water was black and the pool clearly hadn't been opened for a couple years at least.We ended up using gallons and gallons of liquid chlorine, which over the course of about 3 weeks got us to the first picture (aqua green water). The algae was mostly dead and we were just dealing with cloudy water.While keeping the pool at shock level, I decided to add some of this floc to clear up the water. It needed about two days to fully settle and drop everything to the bottom, but as you can see the water is pretty much crystal clear now - truly a lifesaver! From there I just vacuumed to waste, going very slow as to not kick up the dead algae. We have a sand filter which is known for being the slowest at clearing up cloudy water, probably would have taken another week or so of constant filtering to clear it up without this flocculant. I did also add some DE to the sand filter which helped a little too.Perhaps I could have used this floc earlier on in the process, but regardless I am happy with the results. I included the third picture (black water) for encouragement to those who may have a swampy green or black pool. Ditch the pool store, buy liquid chlorine and flocculant - if I can do it you can do it!

    The media could not be loaded.
    Made the mistake last year of letting the pool get green. Thought no big deal, put some chemicals in it. Killed the algae. Strips looked good for levels. And there has been dead algae at the bottom of my pool for almost a year! I have tried all the things. Got a robot vacuum. Tried a hand vacuum. Used a clarifier. Shocked it multiple times. Cleaned the filter over and over. Had the kids swimming in the pool to keep it stirred up and hopefully get pulled in to the filter. Pieces were too small. They just came right back into the pool. Found this product, did a little research and YouTubing about how to vacuum to waste. And wala. Worked like a charm. One day with some tedious vacuuming after the flocculant did its job of
    sinking everything and clumping it and I can see the bottom of the pool again no problem with no more dead algae to cloud up the water anymore! Beautiful clear clean water!

    5.0 out of 5 stars Works for even the most disturbed cloudy icky water !
    Reviewed in the United States on September 7, 2022
    Size: 1-QuartVerified Purchase
    All I can tell you is that this flocculant works, it will sink everything , I was so amazed , following the instructions, dosed it with my measuring cup , poured it into the skimmer and ran the pump for two hours. Turned pump off and didn’t even look at that pool for 20 hours . We had a terrible mishap , a huge flowerpot fell off the deck and nobody noticed it till late at night and the whole pool was cloudy, with so many particles floating in the water, it was hard to see the floor, nothing one can just vacuum up . I was near tears.
    So when I finally looked at the pool again I said wow , everything had settled to the bottom , I mean everything , even the smallest sand particles from inside the potting mix , the bigger debris and the mulch as well. So I went to work and vacuumed very carefully on waste, letting the hose run at the same time and it worked beautifully. I was flocked, hehe . This was the first time I used a <pour in skimmer > flock and I wish I had found this earlier as it is much easier to use as what I had been using. So happy !

    Reviewed in the United States on May 12, 2023
    Size: 1-QuartVerified Purchase
    We've bought all different brands of flock and this stuff is fantastic! Just pour in the measured amount required for your water volume and run it a couple hours. Turn your pump off and within 48 hours the cloudy junk suspended in your water will be all on the bottom and the water will be Cristal clear. Good stuff really. We've purchased 3 bottles of this stuff just to make sure we have it on hand. We've tried other brands and this one is the best so far. Sorry I don't have pictures to share. We've owned this inground 38x26 8ft deep end about 26000 gallons of water for22 years. You can't go wrong with this stuff. This flock and a good quality timed pump that turns the water over a few times a day will save you a ton on chemicals. Try this stuff I think you'll get then results your looking for. Makes it real easy to vacuum up all the ugly stuff that was suspended in your water
