How much do DE pool filters cost?

The average cost of a diatomaceous earth pool filter is between $520 and $1,600, depending on its size and complexity.

How much is a pound of diatomaceous earth? However, if you can’t find a suggestion from the manufacturer, you can use a simple rule of thumb: For a full clean or new filter, add one pound of DE powder for every 10 square feet of the filter. So, a 48-square-foot filter will need about five pounds of DE powder.

Do I need to add DE After every backwash?

If you are replacing DE Powder after a backwash, you will not need to add the full amount – generally around 80%. The grids will have retained some of the DE Power after the backwash, and if you add too much, it may end up in the pool. The best way to assess how much DE Power to add is to monitor the pressure gauge.

Is a DE filter good?

D.E., or Diatomaceous Earth filters remove particles down to 1-3 microns in size, a smaller particle size than can be seen by the naked eye, making them the most effective filter type. The filter contains either fingers or grids (grid assembly shown) that is covered by a fine powder called diatomaceous earth.

How often should you backwash a DE filter?

“When do we need to backwash?” – It is recommended to backwash your filter once every 4-6 weeks of regular use. Additionally, there are several instances that would require backwashing in between the normal monthly backwashing.

Can you put too much DE in a pool filter?

Adding too much DE to your pool may cause multiple negative results. These ramifications include a clogged skimmer, turning the pool cloudy, reducing the circulatory pressure in the pool and putting too much work on your pump that may result in eventually breaking the pump.

What happens if I put too much DE In my filter?

Too much D.E. will result in the D.E. “bridging” between grids — reducing the filter area. This will make the filter less efficient, raise the back pressure, ruin the grids and make the whole circulation system underperform.

How long do DE filters last?

For all of you with DE filters you are probably extremely happy with the quality of water that your DE filter creates. There comes a time when you will need to replace the filter grids. This is usually after 7-10 years of hard work.

What does diatomaceous earth do in a pool filter?

When diatomaceous earth is introduced into the pool filter system, it coats the filter cloth. As water passes over the filter grids, the DE particles capture even the smallest suspended dirt particles. When cleaning is needed, the water flow is simply reversed.

Can I run my filter without de?

If you do not add enough DE to your filter, then the grids are not totally coated with DE and the dirt that goes into your filter will attach itself right to the fabric on the grids and will not backwash off. This will cause your filter to short cycle (go very short times between backwashing).

How do I know if my DE filter is bad?

There are ways to tell if the swimming pool filter is bad. If the water turns cloudy, then you know that your filter is not functioning properly. Leaking multi-port valves, broken or bad laterals, valve failure, tank failure, and pressure issues are some of the other indicators that the pool filter is bad.

Can you backwash too much?

Backwashing a filter too frequently will keep the sand so free of dirt buildup that it will not have the ability to remove the smaller particles of dirt and they will simply pass through sometimes causing cloudiness in water.

Is a DE filter better than cartridge?

Cartridge filters are popular for spas and above ground pools. These filters trap particles down to five microns in size. … A DE filter will work better on smaller particles while a cartridge filter will work more efficiently with larger types of debris.

Can you backwash a DE filter?

DE filters can be backwashed 2 or 3 times in succession, to remove more debris than is possible from just once. After backwashing a DE filter for 2-3 minutes, return the valve in the Filter position, and run the pump for 15 seconds. Then set the valve to Backwash again, for another 30 seconds.

How big of a DE filter do I need?

The filter flow rate must be rated at least the same GPM as your pump, or higher. With pool filters, it’s best to err on the larger size so it can handle the power of your pump. A helpful rule of thumb is to choose a filter with at least 1 square foot per 10,000 gallons pool capacity.
