DE or Cartridge Filter Cleaning Special
For a limited time Only $99

The purpose of backwashing is to remove the old DE, with its trapped impurities, so you can replace it with clean DE. So why do you need to clean the DE filter?

As impurities accumulate in the DE, the combination of DE with those impurities makes a thick, muddy paste that doesn't just "wash out" when you backwash. Over time, especially with repeated cleanups of algae infestations, or even a single cleanup of a horrendous algae infestation, huge hunks of such thick, muddy paste clog the spaces between adjacent grids, and become completely stuck, unable to be removed by backwashing.

Another thing that will further exacerbate the problem is excessively high filter pressure. Excessively high pressure occurs because of in-attention -- the pool owner or Pool Service Technician doesn't regularly check the pressure, and therefor fails to backwash when the pressure goes to the specified amount, instead letting the pressure rise several PSI beyond that. The DE and impurities have been compressed into hard clumps and bonded to the grid mesh. They will not easily be backwashed out.

When you backwash and relcharge, the pressure goes down almost where it should be, but quickly comes back up, even in a reasonably clear pool. This behavior costs a fortune in DE, and also prevents dead algae removal. Without efficient filtering, you can never have a really clear pool.

We therefore recommend that you have your DE Filter cleaned and re-charged every six months. this simple maintenance procedure will extend the life of your equipment, reduce overall chemical costs, and you will enjoy your swimming experience more.
