2405M Flocculant for Pool, 5-Pounds

My problem was hard white foam which appeared after a heavy rain washed a tremendous amount of debris into my pool from the huge pine tree which towers over it. This followed a long period of bad air caused by firestorms in California last year. I laboriously filtered the water and adjusted all the chemicals, so that the water (which was green immediately after the rain) became perfectly clear and odor-free, but the foam was visible whenever I heated the spa. I would remove it with a net about 1-foot square and pile it next to the spa. I could easily remove 50 square feet (50 netfuls) of this hard white foam each time I used the spa. It would form huge piles on the ground that bounced each time I added another netful of foam, much like pudding. The next day I would see green residue on the ground where the foam had been. I was not worried that the foam could be dangerous to my health, but I didn't like it very much.From what I could determine on the internet, the foam was caused by organic matter that had gotten into the water and was too small to be removed by my cartridge filter. I could have kept removing the foam manually repeatedly, but the volume of water in the spa is very small compared to the volume of the pool, and it would have taken forever to remove all of the foam in this way.I had read that Maintain flocculant should not be used with a cartridge filter, but my cartridges were about 9 months old, and I didn't mind sacrificing them. First I took out the cartridges and washed them. There was a lot of green debris on the ground afterwards but nothing out of the ordinary compared to previous washes of other cartridges. Then I replaced the cartridges and set up the pool vacuum. After getting the air out of the system, I turned off the pump. I made sure that the pH was above 7.8 and added 1/2 bottle of this Maintain flocculant, spreading it over the top of the pool. The next day I noticed that there was a lot of white powder on the bottom of the pool, but the water was still cloudy and there was also a lot of powder adhering to the walls of the pool. So I brushed the walls, which caused a dramatic increase in water cloudiness, and waited another full day before vacuuming.On the second day, the water was clear enough so that I could see the bottom well enough to vacuum and there was relatively little flocculent adhering to the walls. I turned on the pump and quickly removed the cap from the opening at the bottom of the cartridge filter. This of course caused a huge amount of water to spill onto the ground around my pool equipment. Then I rushed over and started vacuuming the pool. When the vacuuming was complete, I quickly turned off the pump and replaced the cap. Then I refilled the pool with tap water. The pH dropped to about 7.4. I filtered the water in the pool to remove the cloudiness.The next time I turned on the spa, the foam problem was greatly reduced but not eliminated. I could still remove about 10 netfuls of foam each time I heated the spa. So I washed the cartridge filters again, but this time they seemed quite clean, and there was very little white material on them, suggesting that they had not been affected by the flocculent which had been able to escape easily through the bottom of the filter.Since I still wasn't satisfied, I added the other half of the bottle of Maintain flocculant and repeated the above procedure. This time, I achieved a further reduction of foam, to about 5 netfuls each time I used the spa, but the difference was not as dramatic as the first time. In retrospect, I should have used the entire the bottle of flocculant the first time. Finally, after filtering the pool thoroughly with the old filter cartridges in place, I replaced them with new ones.In conclusion, I was able to prove that it's OK to use flocculant with a filter cartridge, as long as you're willing to replace your cartridges, and it seems to me that replacing the cartridges might have been unnecessary, since they did not appear to be very much affected when I cleaned them after the floc treatment. I also demonstrated that flocculant can greatly reduce, but not eliminate, the hard foam problem that I've been experiencing.

My pool was in a condition that not even Yoda would have been able to help with. "This is my swamp" I used to say when people would ask about it.After neglecting it from fall to spring, it was full of all sorts of nasty stuff.Anyhow, this stuff works. Here is how I went from a swamp to a crystal clear swimming pool.Step 1.Kill everything. Nuke the pool with chlorine tablets in the pump/floater/vacuum. Use aglaecide, lots of it. Shock the pool with more shock than can be considered safe or reasonable.Step 2.Remove as much big debris as possible. Scrape the bottom with a rubber-spatula net. A big net with a rubber fin thing that helps scoop stuff into the net without damaging the pool.Step 3.Fix the Alkalinity levels. Dont worry about PH yet. Fix the alkalinity and that will help the PH anyway.Step 4.Turn filter to bypass, Add the flocc to the pool, run the pump for 6 hours, then shut off the pump and let the pool sit. The reason to run the pump is to help mix up the flocc with the water so it gets all over.Alt Step 4.If you cant bypass your filter then premix the flocc in a 5 gallon bucket of pool water. If your pool is big enough to do a whole can of flocc then split it between two 5 gallon buckets.Step 5.Wait 12-24 hours. Just let it sit and do its thing. If its not working it didnt mix well with the water. If your pool foams up its because its going through the filter and not bypassing it.Step 6.All the gross stuff will be on the bottom. Set the pump to empty and use a hose vacuum to suck up all the gross stuff at the bottom. You need a strong vacuum for this and it will waste probably around ~500 gallons of water. My pump didnt have a way to do this so I used a gas powered water pump and some hoses to shoot the water into the yard.Step 7.Fix the PH. Run the filter and be ready to backwash it 3 to 4 times.

This product cleared my incredibly cloudy pool. My DE filter was needing to be backwashed every 30 minutes and I thought I was never going to get it clean. Did some googling and learned about floc. This one was the fasted delivery. Here's what I did for my ~30k pool.1. Set pump to recirculate **important** if you leave the pump running2. Dumped entire 5lb container into 5 gallon bucket w/ pool water.3. Mixed it up for a bit4. Dumped it into one of the skimmers.5. Let run for an hour, then turned off the pump6. Left overnight ~ 12 hours.7. Vacuumed all the crud that sunk to the bottom to waste. There was a LOT of it!I can't believe how well it worked!

Es un producto muy eficiente y cumple con su propósito que es decantar las partículas de la piscina. Lo recomiendo.

I tried 2 other floculents for grey dust removal ( dead algae ) this product was exceptional. After 12 hours all the particles were traded in heavy clumps , after vacuuming, I could still see the main drain, any disturbance quickly fell to the bottom . I will have a spare container on hand .

Of all the pool products over used over the years, this one was a complete waste of money. Did not floc the pool at all! Don’t know if I received a poor batch but after 2 attempts a month apart I got the same results… a bunch of powder on the floor of pool that did not do what it wasn’t supposed to.

I got this in hopes of gathering the dust in my pool and while it did pull the dust together it didn't create a ball or make it really firm or hard but it worked enough to help the process of getting the dust out.
