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.

What happens if you run a DE filter without DE?
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 long do DE pool filters last?
Pool Filters With proper preventative maintenance, the non wear out parts of a filter should last between 5-10 years as well- these include the band clamps, the internal grids, and plumbing including valves.
