Perlite 4212 Filter Powder D.E. Alternative for Swimming Pools, 12-Pound

Great product for my pool filter

I tried this product after my local pool dealer told me that my old d e pool filter was no longer available New York and California were going to discontinue any use of the d e products he tried to sell me a sand filter and pump I've had my pump for over 12 years along with the DE filter I continually had to get rid of the old d e and put in new de in order for the filter to run that is recommended 12 PSI the pump keeps slowing down I thought it was time for a new pump but I thought I give this product a try the stuff is wonderful my filter and pump are working better than they ever did my pool is crystal clear the stuff is amazing I'd recommend it to anybody with a d e pool filter

I have used diatomaceous earth for 45 years. I read about the risk of silicosis from DE air borne powder so I decided to switch. I tried a fiber material but I prefer this pearlite product. It is just like DE and easy to use. I have been using it for a couple of years and feel it works as well or better. I also don’t have to be concerned with disposing of it.

I switched to this from standard earth. Keeps the water even more clear than I expected

(+): Perlite filters great in my 15K gallon pool with the ability to easily rinse and wash away during a backwash or filter tear down. It’s also lighter in weight, which makes tear down a bit easier too. I notice that my pool seems to stay more clear and the time between filter cleanings as decreased by 10-20%. Flow rate (more water flow) is also much better, with 25% increase across all pump speeds. This is especially noticeable in the jacuzzi with the force of the jets. (-): No matter what I do, the Perlite always flows into the pool when adding through the skimmer. Also, it seems to quickly cloud the water a bit upon initial recharge, but clears up within a couple hours. With DE, I’ve never had this problem. I do occasionally get the “white balls” on my glass tiles, but either I wipe them off or they dissolve with 7-10 days.
