Can I Put De In My Sand Filter

Hayward Perflex Diatomaceous Earth Pool Filter

Yes, you can put a small amount of D.E. powder into your sand filter after each backwash to help improve its filtration temporarily. But you assume some risk because sand filters are designed to be used with sand and it might void your filter warranty. And always start with a small amount, because too much will clog the system and possibly ruin it.

When To Backwash A De Pool Filter

You should backwash your DE pool filter about once a month during pool season. In addition to the regular schedule, youll want to perform additional backwashing if:

  • Youve been running your pool filter for 48 hours straight. This can cause a pressure build-up, even if the filter grids look clean.
  • Higher-than-normal amounts of debris have entered your pool water. A heavy summer storm that washes sediment into your pool or a large potted plant that tips over into the pool can overtax the DE system.
  • Your pool has had a heavy swimmer load for an extended period of time. If youve had houseguests for several days or your kids had friends over every day of the week, youll need to clear out the remnants from all the extra sunscreen, beauty products, and even sweat that will clog up your DE filter.

Pro tip: At least once during each pool season and anytime your filter pressure remains high after backwashing take the grids out of your DE filter and clean them more thoroughly.

Why Does My Filter Pressure Rise Very Quickly Even After Backwashing

  • D.E. filters filter the water down to 1-3 microns, every time the water passes through the filter. Maintain a balanced clear pool and this will reduce incidents of rapid pressure rise. One possibility is that the filter grids or Flex tubes are clogged with minerals or oils. You should clean your grids once a year, or season, with a degreaser and if needed an acid bath. Minerals and oils embed themselves in the fabric of the filter and reduce the available surface area used for filtering.
  • If too little DE is added during pre-coat, debris and particles will embed in the fabric. Cleaning with a high-pressure hose, NOT A POWER WASHER, may be needed to remove the grids. If cleaning does not work, then replacement is the only option.

Hayward Perflex 1 Hp Diatomaceous Earth Filter Pump System

The Hayward Perflex Above Ground Pool Filtration System is designed to pair easily with above ground pumps to maximize filtration and deliver clearer water than ever before. This advanced filtration system is designed to operate with less resistance than conventional units, producing more filtered water with less pump power. Includes a 1 HP PowerFlo Matrix pump, a modular platform base, a connector connection and a 1 12 hose package.

How Does A De Filter Work

A D.E. filter uses diatomaceous earth as the filter media. What is diatomaceous earth? Its the fossilized remains of diatoms, a kind of aquatic creature with a skeleton high in silica. D.E. powder is sold at most pool and hardware retailers, so its easy to find and its affordable, too.

When D.E. powder is added to the filter, it attaches to the grid or fingers inside the filter, creating a D.E. cake. And this cake, along with the filter grids inside, helps filter out fine particles in your pool water. This makes a D.E. filter the most powerful filtration system, compared to sand or cartridge filters.

Over time, the filter element will get dirty and contaminants will build up in the D.E. powder. And unfortunately, cleaning a D.E. filter requires multiple steps compared to other types.

To clean a D.E. filter, youll need to remove the D.E. grid and spray it down with a garden hose or soak it in muriatic acid to remove oil, minerals, and dirt.

Youll also need to regularly backwash the D.E. filter to help remove the buildup thats accumulated inside. That means reversing the flow of water inside the filter, which loosens the collected dirt and debris to leave the tank. That water is then sent out of your pool using the filters waste port.

Finally, when youre replacing your grids or backwashing the filter, youll need to add more D.E. powder. This is added directly through the skimmer line where it then travels into your filter.

For Backwashing Your Filter

To keep your pool in tip-top shape, you should backwash your filter every one to three months. Backwashing isnt a complete clean but simply removes the buildup of residue on your filter grids. A lot of the old DE powder will come off, so you need to replace it with fresh powder.

Backwashing doesnt remove all the DE powder on your filters, so you dont have to add as much as you would for a new or thoroughly cleaned filter. You only need to add about 80% of the amount you would for a new filter. So, a 48-square-foot filter would need a little less than four pounds of DE powder.

De Filters Vs Sand Filters: Which One Is Better

Both D.E. filters and sand filters use powder or sand to capture particles to clean your water. And whether you use a D.E. or sand filter system, youll need to backwash each one regularly to help remove the dirt, debris, and dirty water.

But when compared to a sand filter, D.E. filters provide much better filtration of smaller contaminants. A sand filter will filter particles ranging from 20 to 40 microns in size, whereas a D.E. filter can handle particles as small as 1 to 6 microns. Things in your pool water like deodorant and other cosmetic products can be as small as 6 microns. And skin flakes can range from 0.5 to 10 microns. So while these might pass through a sand filter and end up back in your pool, theyll be captured by a D.E. filter.

However, while a D.E. filter will take care of smaller particles, you can expect more maintenance, more cleaning, and a higher upfront cost.

While youll only need to backwash your sand filter for regular maintenance, a D.E. filter is more involved. D.E. filter grids require cleaning, which means taking apart the filter and spraying down your grids with water or soaking them in muriatic acid. And after each filter backwash, youll need to add more D.E. powder.

Finally, sand filters are one of the most common types of pool filters. That also means the initial investment is much more affordable than a D.E. filter. However, youll need to replace the sand or D.E. powder in both types of filters every 4 to 5 years.

Hayward De Filter Models And Parts

Hayward DE filters contain diatomaceous earth, which is mined and is the fossilized exoskeletons of tiny diatoms. They are used to coat “grids” in the filter housing and act as tiny sieves allowing for the removal of debris as small as 5 microns. Once the pressure rises, the filter is backwashed just like a sand filter and then “recharged” with more DE powder. DE filters trap debris as small as 2 – 5 microns.

Hayward D.E. filters offer superior water clarity, ease of maintenance and dependability. There are different Hayward D.E. filter assembly models available:

  • Pro Grid Series – Pro-Grid vertical grid D.E. filters provide superior water clarity, efficient flow and large cleaning capacity for pools and spas of all types and sizes. View Pro Grid parts diagram.
