    Add 1 pound D.E. powder per 10 sq ft of filter location. Look on filter tank.

Tips

  • An adequately sized D.E. filter should, normally, be able to operate continuously for a period of four weeks between back-washings. A "Filter Run" of not as much as 30 days may suggest grid problems (or sizing problems). Filter grid material may become clogged with calcium deposits or oils. After getting rid of the grids from system, you are able to drench in TSP (trisodium-phosphate) and tepid to warm water to remove greasy build up. By using Baquacil or SoftSwim, and you will soak the grids in a 10% muriatic acid answer for a few minutes followed by a full wash. TSP immerse and wash will eliminate calcium deposits such as for example calcium.

Warnings

  • Eliminate altering jobs on the multi interface valve while the pump is operating.
  • Usually do not put D.E. back in one's body by putting it in filter, add your D.E. toward skimmer.
