Clean Fingers Of DE Filters
by Lori
Question #2 Is it possible for a fine white film to build up on bottom of pool from the DE when recharging the filter, if so what is wrong with the filter? Thanks for the question Lori Under normal use and good weekly maintenance, the actual DE filter can last up to 25 years. You should expect the DE grids or fingers to last at minimum 4 - 5 years. This is with proper maintenance and cleaning. Some may last less because of overuse or not using enough DE, too strong a pump (this can tear the grinds or fingers), not cleaning or infrequent back washing, putting DE straight into the skimmer (not first making a slurry) etc... There could be many reasons why DE is going back into the pool after you recharge the filter. This is a very common problem with DE filters. Here are some posts to look over: How Do I Vacuum And Remove D.E.? Pressure Builds Up In 30 minutes And DE Flowing Back Into The Pool Cleaning Pool Bottom Is Difficult With A DE Filter WHY AM I GETTING DE BACK IN THE POOL? As you can see lots of people have this problem. Some reasons for DE returning to the pool are: Torn filter grids/fingers - Remember to check the end of the grid. Broken manifold Broken and/or missing air relief strainer If you're having DE returning to the pool, please look over the above posts.
