DE (Diatomaceous Earth) filters should be cleaned with special products at least once every season. Perform a complete cleaning and inspection yearly. Check the pressure gauge to figure out when it’s time to backwash; the more debris is in your filter, the higher the pressure will be.
How often do DE filters need to be cleaned?

Do you have to add De Every time you backwash?

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.
How often should you backwash a DE pool filter?
Bottom line, the filter must be backwashed on a regular basis to ensure that your pool water is clear. “When do we need to backwash?” – It is recommended to backwash your filter once every 4-6 weeks of regular use.

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.
Is it safe to swim with DE in the bottom of pool?
The DE is safe and poses no health threats, it is just unsightly and spoils the pool’s aesthetic.
Can you put too much DE in a pool filter?

How much de do I add after backwashing?
After a backwash, to get the amount of DE powder, simply take the recommended amount of DE powder for a new filter and multiply it by 0.8, or 80%.
Why is De blowing back into my pool?
DE Blow-Back: If DE powder is coming into the pool, you may have torn filter grid fabric. Or, you could have a cracked top manifold, or missing air bleeder. The standpipe o-ring could be missing, or the filter valve could be allowing some DE powder to bypass the filter as you add it new.
Can De filter get clogged?
DE filters, no matter which type used, will clean water down to one to three microns. It is important to remember this, because all DE filters sometimes are faulted for short cycling, or clogging up too quickly.
Does diatomaceous earth clog drains?
Diatomaceous earth cannot be discharged to surface waters, storm drainage systems, septic systems or on the ground. If there is not a suitable dirt area, discharge filter material back into the sanitary sewer system using a clean out.
