How do I know if my pool filter needs DE?
Add diatomaceous earth (DE) to your pool skimmer, stick to around a scoop or two – no more than the size of a 1lb coffee cup. The moment you do this, go to the pool jets to see if it is returning DE into the pool, or if the water suddenly looks cloudy. If it is, you likely have an issue with your filter.
What is the purpose of DE 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.
What happens if I don't put DE in my pool filter?
Do not operate your filter pump without having the D.E. powder coating the grids, or you will see the filter pressure rise very quickly, and if left in this manner the grids can collapse or the fabric can become clogged or damaged. As the pressure gauge on a D.E. filter increases, flow rate decreases.

How often should I add DE to my pool filter?
The D.E. needs to be replenished once the filter is turned back on. Every three months the filter should be taken apart, the grids should be hosed off, and visually inspected for any rips or tears that will cause D.E. to blow back into the pool.
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.

Answer: It is not recommended to swim in the pool when DE is present. It is more dangerous in dry form when it is in the air and breathed in. However, people do swallow water when swimming and swallowing DE is always the danger with it.
How long do DE filters last?
DE filter grids can last for four or five years with proper care. During cleaning, the grids need to be looked over for damage. Tears in the grids can cause the diatomaceous earth to flow back out into the pool water. This shows up as a white or gray powdery substance on the bottom of the pool.

What is a DE Filter?
A diatomaceous earth filter (DE filter) is composed of several grids that hold the diatomaceous earth powder. They are sometimes known in the business as "water polishers" since they are capable of filtering particles as small as three microns (in comparison, a grain of salt is about 90 microns in size). Anything smaller than 35 microns is invisible to the naked eye. This is why I tend to rave so much about DE filters. They are by far the best filtration available for swimming pools.
How to backwash a DE filter?
Backwash DE Filter Steps 1 Before you reposition the "multi-port" valve, be sure the pump is off. 2 Select the "backwash" position, then turn the pump on. 3 Backwash for three minutes. This will get a lot of the old DE powder out. 4 I usually return the valve to the "filter" position, run for another minute, and then backwash again for another minute. This ensures the filter grids are clean. 5 With the valve positioned back to the "filter" position and the pump running, you will add around four pounds of DE powder through the skimmer. (Consult your DE filter's owner's manual to discover your filter's square footage and exactly how much powder to add.)
How much powder to add to a DE filter?

What is a DE filter?
DE is a natural, fine powder made up of fossilized skeletons of tiny organisms called diatoms. DE particles are very porous because of the hollow nature of those organic structures. They are very well-suited for filtering water, and they can capture extremely fine debris.
How does a DE filter work?
A DE filter has a set of grids inside the hollow tank, held in place by a top and bottom manifold, pressure plates, and a gasket. The grids have fingers that need to be coated with DE for them to filter the water properly. Once coated, dirty water is forced through the DE-coated grids, trapping debris. The clean water then exits the filter tank via a valve and heads back to your pool.
How Long Do DE Filters Last? And When Is It Time to Replace Them?
DE grids can last many years. The fabric of the grids tends to become brittle and deteriorate after ten or so seasons. Though, some users may get more life out of a set while others might not.

How does a pool filter work?
Water enters the filter tank through a series of valves or a multi-port valve. The water is then directed to the bottom of the tank without touching the grids. This action collects the DE on the bottom of the tank and depositing it on the grids. Suspended dirt gets trapped on the DE powder as the cleansed water passes through. The water that leaves the filter through the output port is then returned to the pool.

Small amounts of DE can be added to a High-Rate Sand Filter after each backwash to add efficiency to you filtering normally lost with sand. Figuring out how much DE to use: 1 Start by noting the PSI reading on the filter with the pump running. 2 Mix 1/4 cup of DE with water in a bucket and pour that slowly into the skimmer. Remove the skimmer sock, if any, before adding DE. 3 Give the system about two minutes to stabilize. 4 Note the pressure on the filter and repeat the second and third steps until the pressure has gone up by one PSI. This will typically take around 1-2 cups of DE.
