    • Great product
This product is absolutely amazing! If you follow all the directions on the package it will clear extremely green water over night. I have used this several times now over the last year and it works every single time. I highly recommend this product to to anyone who has issues with green water.

    • Absolutely a most when opening your pool!
This is the best starter kit! Everything was in the kit with no leakage of the products. Product dissolved quickly. We let our pool set over night before vacuuming the bottom. And vacuum slow for the best results. We've used this product every year for the last 5 years!

    • This works!!!
My pool pump had died and my water turned green before I could get it repaired. This stuff works!! Pump died twice, bought two of these, one each time. Definitely works wonders. Dead algae lands on the bottom, allowing you to siphon it right out - DO NOT use your filter, just siphon it out to the ground. ... show more

    • Took 48hrs but did the job
After recent hurricane, our pool was filled with a ton of debris. Without power too, the filter pump was off which made the build up of algae and everything worse. Usually we keep the salt water inground pool water well balanced and clear. Even after getting as much of the debris out and scrubbing after about 3 weeks, the water remained dark green. We have a cartridge filter so instead of following the instructions exactly on the box, after adding the ingredients per pool size, we manually used the pool brush to mix around for an hour. In 24hrs we were able to see some to the bottom. In 48hrs we saw the clumped dead algae more at the bottom and less green on the pool walls. The clumps were hard to vacuum out though as it would disintegrate easily. Ended up turning filter on and then having to wash out all the mess caught in the filters for second time since the hurricane. After that, pool was back to clean and clear while balancing out the regular items. If you have a cartridge filter and use this then be ready to either wash out the clumps or having to replace them. We were able to wash them out but the product is not recommended for cartridge filters. Also will require extra time if unable to change water flow. ... show more

    • Not for cartridge filters
It's a great product for a sand filter. Do not use if you have a cartridge filter. The second step of this is like a sand and your pool vacuum will not get it. It works great to clear the water though!

I have been fighting algae in my pool for a month! It started small and just kept growing and growing. I will always use this no matter if it is a tiny amount of algae or a massive bloom like what I ended up with. Pictures are in order.. First pic is when I was adding in Step 1, I removed my filter cartridge from my pump and just used that to help circulate. Left step 1 in for an hour before I added step 2. Ran the pump for a bit, then turned it off (about 6pm is when I started) by morning everything was on the bottom! I vacuumed 24 hours later (becaese that is when I had free time). I kicked up some algae during vacuuming so I was worried I would have to repeat the process again, but I let the pump run (with no cartridge) overnight and the next morning everything I had kicked up was settled back down to the bottom so I could just vacuum one last time!!! My pool holds about 9K gallons, it was a little low when I started, but I only lost about 6 inches of water in the vacuum process (vacuum to waste!!). I also only used half the contents of the box. So for roughly $14 my pool looks beautiful again!! So simple!!! ... show more
