How do you measure DE LB?

Most DE filters require 1 lb of D.E. (diatomaceous earth) for every 10 square feet of filter area. For Example, if you have a 48 square foot D.E. filter than you would typically need 4.8 lbs of D.E. The D.E. Scoop helps you quickly measure the correct amount of D.E. for your filter.

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.

Can I 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.
