They are very well-suited for filtering water, and they can capture extremely fine droppings.

A DE filter has a set of grids inside the hollow tank, held in place by a top and bottom manifold, pressure plates, and a gasket. The grids take fingers that need to be coated with DE for them to filter the water properly. In one case coated, dirty water is forced through the DE-coated grids, trapping debris. The clean water and then exits the filter tank via a valve and heads dorsum to your pool.

The grids tin ofttimes be agitated with a crash-land handle or other machinery that basically shakes the DE around on the fingers and exposes fresh powder to the water, helping it last longer. When the DE accumulates too much fine debris, it's fourth dimension to backwash, just like a sand filter.

Unlike a sand filter, you still accept a chip of piece of work to practice afterwards backwashing. Earlier yous tin start filtering the water again, y'all have to add together a new dose of DE to the puddle filter.

Adding DE is done by pouring some into the skimmer's mouth, the amount varies past model, but a typical ratio is approximately one pound of DE to every five square feet of filter grids. Doing and so is a scrap of a messy job, and information technology is inadvisable to inhale DE.

You may even want to article of clothing gloves, goggles, and a mask to avoid irritating your hands, eyes, and lungs.

DE Filters vs. Sand Filters

DE filters and sand filters are similar in that they both need to be backwashed periodically. But, sand pool filters tin can typically run a bit longer before they demand a backwash to clean them. They both are equipped with a valve to adapt the menstruum of the h2o and make backwashing possible.

Dissimilar a DE filter, y'all do non lose sand from your filter when you backwash. It all remains in the tank. When backwashing a DE filter, y'all actually rinse abroad all of the DE, forth with the dirt defenseless in information technology. That ways each fourth dimension you backwash, you also have to add a new DE to a DE filter system.

Since some people are very sensitive to exposure to DE, information technology can be a bit of a hassle to work with when adding it to the system. It's too not a good thought to inhale DE if yous tin can avert doing so, equally the dust tin't be healthy for your lungs.

You can ever vesture a particulate mask to minimize whatsoever health risks, just that does add another step to the job, and y'all'll exist working with DE quite often.

DE filters also have a grid system, and sand filters do not. So, in addition to the expense of DE itself, you may take to supplant the grids periodically if they develop a rip or begin to deteriorate.

DE Filters vs. Cartridge Filters

If you lot're considering a cartridge filter, make sure to read our guide on replacing your pool filter cartridge.

Just, DE grids can be rinsed via backwashing between heavy cleanings while cartridge filters tin can't. DE also filters down to a much effectively level of debris than either sand or cartridge filters. So, backwashing needs to be washed quite regularly.

A DE filter tin't continue your water clear and clean after it gets chock-full with droppings, and the tank pressure will build chop-chop. Y'all should expect that a DE system will require a lot of backwashing when the pool is quite muddy, similar when you first open it each flavour or later a heavy storm.

In some cases, that volition mean multiple backwashes every day until the h2o clears upward. And you will likely accept to backwash after each vacuuming.

Lastly, DE filters are typically much more than expensive than cartridge filters.
