Cesco Solutions FC-100 Flocculant Clarifier - Water Flocculent for Swimming Pool, Pond, Spa- Pool Supplies (5 Gallons)

So we use rain and fill water in our pool since we are well water. We have been fighting dust for a while now and this took the cloudy pool to crystal clear and dirt all on the bottom in 1 treatment. It’s taken a few to fully clear the pool since it’s large, deep, and the sand didn’t catch all the dust part lives the first few times and redeposited some but certainly has made a huge difference more than other brands. Easy to understand directions and calculations and don’t need much for a large pool really. Worth its weight!

We use this for our pool when it gets cloudy. It takes so the small particles to the pool floor so they can be swept up. Works great

I've been using this for several months to keep my 45,000 gal salt water pool clear, and it has worked well enough. The pool has a DE filter so normally runs clear, but a couple of weeks of significant rain meant I had to pump water off the pool several times, and as a result diluted the salt water with plenty of fresh (rain) water. Getting the chemistry back meant adding salt, calcium, and all the usual chemicals to restore the balance- along with frequent back-flushing the DE filters. I often had hazy water and added this floc to clear up the water, which is did reasonably well. It might be my pool cleaner, it might be this floc, it might be the pool chemistry, but I felt that I added fully 50% more of this floc to get results. Not a real problem as the product isn't expensive, but in general, be prepared to use a lot of this product.

Does attach to bacteria but does not drop to the bottom of the pool... not good for above ground pools as the pump doesnt have enough power to draw the bacteria to the filter

Great price when you're on a budget especially these days

Super easy to follow directions to follow, however the solution did not help settle particles in order to help clear up the pool water. It in fact became more cloudy. Super disappointing… 😏

Cleared the water quickly

After 48 hours in the pool, expecting some degree of flocculent effect and having watched it closely ever couple of hours during those days, this product did absolutely NOTHING to help take particles to the bottom of the pool for vacuuming. The "ecological" label might make someone feel good about the purchase of this product instead of a traditional flocculent, but it apparently means it's just a jug of green goo that does nothing but make you feel ecologically responsible. But it sure doesn't help with the cleaning of your pool. Angry for wasting $40 on this useless goo. It's irresponsible to label this as flocculent. Shame on you Cesco, for marketing this useless product like this. I wish there were an option to select a fraction of a star. Lowest rating possible!
