Simply put, Diatomaceous Earth (DE) are the bones of tiny little animals that lived millions and millions of years ago, diatoms. This DE is used to coat the "grids" inside the DE filter which captures and filters particles as small as 5 microns. When the filter pressure rises, the swimming pool DE filter is backwashed in the same manner as a sand filter. A slurry of DE is put into the skimmer to "recharge" or "re-coat" the grids of these swimming pool DE filters. This type of filter is effective and efficient but a little more expensive to maintain. Some call it the "water polisher" of pool filters.

I'm figuring you're asking this because you have a DE filter. Basically there is a "cloth filter" in the DE filter. Then (after it has been cleaned and hosed off of all the old DE etc.), you put the appropriate amount of DE into your leaf basket at the pool when the filter is running. The DE will dissolve into the water then collect on the surface of the filter. After that only very small particles (like water etc.) can make it through the filter, which now consists of DE and the filter itself.

How do you get DE powder out of the pool water?
Firstly you find out how the DE got into the pool - must be a broken filter pad. Fix that, then vacuum the pool. No point vacuuming before you fix the filter problem, or the DE will finsih up back in the pool.
Is Salt filter better than DE filter for pool?
Salt is not a filter, it is added to pool water to allow a chlorine generator to operate.
Why would a DE pool filter pump the DE back into the pool via the water jets as soon as DE is put into the skimmers instead of adhering to the filter?
Check the grid and manifolds for holes or cracks.

How do you back flush a pool filter?
Hayward Why is DE getting in your pool?

Can a pool filter cause a pump not to work?
no
Can a pool with a salt generator be used in conjunction with a DE filter?
Yes
How do you remove gasoline from swimming pool with a DE Filter?

How does a cartridge pool filter work?
A cartridge pool filter works by collecting the particles filtering through the pool. It allows water to pass through, but not solid objects.
Can you use diatomaceous earth in a sand filter?
This is a bad idea. Diatomaceous earth (de) will go right through a sand filter. It will end up back in the pool and then it is almost impossible to get out. Sand goes in sand filters, de goes in de filters.
If your DE filter is bad and there is DE entering the pool can you use it without DE until the new filter you ordered arrives?
To be honest you're best off just dosing the pool will a few litres of chlorine and letting it sit. The chlorine will prevent it from going green. Without DE powder it won't filter properly and you'll find you have pressure issues with the pump and filter.

Why is my pool cloudy?
Any particles in your pool can cause cloudiness - for example, dead algae. To eliminate it, most pool stores sell a "clarifier" - the one I sell is blue - which will get the particles out of your pool, or "alum" or "floc", which will bind the particles together, making them heavier, dropping them down to the bottom of your pool. You can then vacuum them out with your filter set to waste. If you have a DE filter, and you add a white powder to your skimmer sometimes, it is possible that your filter is leaking DE back into your pool and you need to replace the grids inside it.
