There's also the Pentair Quad DE filters that are cartridge filters that use DE. My understanding is the cartridges have less pleats that make them easier to clean than standard cartridge filters.
True. My super jumbo CCP520 with 4 huge carts takes me an hour to clean. It's a 1 person job until time to reassemble, when a 2nd person is helpful for the last 10 minutes. With an auto-cover and hairnets in the skimmers, this is an annual task.Pool companies like DE filters because they can backwash them in 15 minutes and clear any problems and be gone. A cartridge filter requires much more time to break it down and clean it so pool companies don't like them.
So is cement if the dust is inhaled. For that matter, chlorine and MA are no bueno either if one was to huff them. Any of the 4 can be rinsed off harmlessly when used properly and with an ounce of care.You all realize DE is a known carcinogen right? Advising ppl to add a little to their sand filters imo is bad advice
You all realize DE is a known carcinogen right? Advising ppl to add a little to their sand filters imo is bad advice. There are cellulose products that can be added to aid in filtering and aren’t harmful to the environment or humans.
PM, your point is understood. The TFP article does highlight the hazards associated with DE. Much like any other chemical or potentially hazardous cleaning process/product, pool owners are ultimately responsibility for a product's use and disposal. Safety is always #1.And where are most ppl putting the DE after they clean the pleats?
DE is a very fine powder which can cause skin irritation and is classified as carcinogenic when breathed in. Some areas prohibit the release of DE into sewers or the environment. Follow handling precautions as indicated on the product packaging. Gardening DE, while safer to handle, has not been heat treated and therefore is not suitable for use in pool filters.
Sand filters are 25 microns........ Human visibility 40 microns
About the only way to tell the difference is to look at the water in front of the pool light at night. You'll see less particulates with a DE filter. But that's about the only way.
Can you see one fog or smoke particle? I can't. You can see billions of almost anything. I can't see atoms either but some how I can read this computer screen. I think you understood what I posted was used as a reference of scale. Thanks for all your help clearing basicly nothing up here for us.Fog particles are 1-5 microns. Smokes particles are even smaller. I guess people who claim to be able to see fog or smoke are just kidding themselves.
You appeared to be suggesting that all filter types can filter particles smaller than the limits of human visibility, and that therefore there will be no visible difference in water quality between filter types.I think you understood what I posted was used as a reference of scale.
