Swimming Pool Care

DE pool filters ((Diatomaceous Earth) are probably the best choice for swimming pool care, maintenance, and swimming pool chemistry.

Simply put, Diatomaceous Earth (DE) are the bones of tiny little animals that lived millions and millions of years ago, diatoms. DE pool filters are the most effective pool filtration available but on the downside, it also requires the highest level of maintenance.

This DE is used to coat the “pool filter grids” inside the filter which captures and filters particles as small as 5 microns. When the pressure rises, it is backwashed in the same manner as a sand filter. A slurry of Diatomaceous Earth is put into the skimmer to “recharge” or “re-coat” the grids.

This type of filter is effective and efficient but a little more expensive to maintain. Some call it the “water polisher” of pool filters.

Pros:

Gets your water cleaner than either sand filter or cartridge filter

DE is easily stored

Recharged easily by putting the DE in the skimmer

Might go longer in between a normal backwash than sand filters

Filters particles and debris better than sand or cartridge filter systems

Cons:

Backwashed every 4 weeks or so

Uses up to 50-150 gallons or more of water with every backwash for an above ground pool and 250-500 gallons for an inground pool

DE must be purchased and stored

Filter must be taken apart and the DE pool filter grids cleaned on a regular basis

The grids need to be coated with fresh DE with each backwash

What Is The Best Filter For You

So, out of the three pool filters, sand, cartridge, and DE, which is best for you? Thinking about changing to a different one? Well, this all depends on your needs, situation, pool use, cleaning schedule, time investment, financial considerations, etc...

Helpful hints:

Want an inexpensive and easily maintained pool filter? Splashing around for fun and it’s just the two of you? Then you may want to consider a sand filter.
You require low maintenance and pretty good filtration? The major use is only on the 4th of July and Memorial Day? Then a cartridge filter is the one you might consider.
Money and time are of no consideration and you want the cleanest and sparkliest pool in the neighborhood. You want to throw a dime in the deep end and be able to see what year it was made. Then check out a DE filter system.

It really depends on your wants and needs. Just remember to ask the right questions to get the best pool filter for your swimming pool.

If that happens to be a DE pool filter, then good for you.
