Are You Adding Enough DE? Probably Not! When you recharge a DE filter after backwashing, you need to add one pound of DE (diatomaceous earth) for every 10 square feet of filter area. This means that if you have a 60 square foot DE filter, you need to add 6 lbs of DE after backwashing. Many people make the mistake of not measuring out their DE properly. The best way is to get an orange one pound DE scoop from one of our stores. If you are using a coffee can to measure out your DE, it is important to remember that a one pound coffee can contains only one half pound of DE. Many times people assume it contains a full pound of DE and then end up adding only half as much DE as their filter actually needs.A DE filter needs a full amount of DE so that the grids are totally coated in DE. If you do not add enough DE to a filter, then the grids do not get the proper coating. This results in dirt becoming impacted in the grids, and this dirt will not backwash out. The end result is that the filter grids get clogged up and the filter “short cycles” – meaning that it goes less than 4 weeks between backwashing and less than 6 months between filter cleans. Bottom line . . . when you backwash a filter, carefully measure out your DE. Your filter will do a much better job on your pool and will last longer between backwashing.
