Will backwashing thoroughly clean my DE filter?
When a DE filter is properly backwashed you will be removing about 80-90% of the DE. Remaining DE may be clumped in the corners of the filter or caked in the middle. This is common. After backwashing, new DE must be added to the filter. Add the entire amount of DE the filter recommends. If you see DE 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 DE going back into the pool.
The only way to remove the entire DE is to disassemble the filter. The next time the filter is disassembled and cleaned, pre-coat with the entire quantity of DE. Remember, the filter should be taken apart and cleaned at least once a year.
