Will backwashing thoroughly clean my D.E. filter?

When a D.E. filter is properly backwashed you will be removing about 80-90% of the D.E. The remaining D.E. may be clumped in the corners of the filter or caked in the middle. This is common. After backwashing, new D.E. must be added to the filter. Add the entire amount of D.E. the filter recommends. If you see D.E. returning to the pool, vacuum it to waste, after it settles. The next time you backwash and recoat, decrease the amount by 1 pound. This will avoid D.E. going back into the pool.

The only way to remove the entire amount of D.E. is to disassemble the filter. The next time the filter is disassembled and cleaned, pre-coat with the entire quantity of D.E. Remember, the filter should be taken apart and cleaned at least once a year.
