After the filter has been backwashed, the filter valve is switched back to filter and the DE is added to the skimmer. The amount of DE to use should be shown on the filter and depends on the size of the filter area. The DE should first be mixed in a bucket with water then poured into the skimmer with the filter running.

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.

Why does my pool filter blow dirt into the pool?

I assume you have a sand filter if so you most likely have broken laterals in your filter. A lateral should allow water through but not sand. if you have a DE filter and you are getting what appears like sand in the pool, you have one or more of the filter grids that have holes and the DE is passing through the filter grids back to the pool.

What is a DE swimming pool filter?

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.

How does a DE filter work on a pool?

Better people than me can explain this. Try 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.
