Frequently Asked Questions
How does the 100 sq ft Quad D.E. compare to the 80 sq ft model (188593)?
Both are Pentair Quad D.E. cartridge-style filters with the same 160 GPM flow rate and 2-year warranty. The 100 sq ft model has 25% more D.E. cartridge area — holding more dirt before cleaning is needed and requiring 10 lb of D.E. (vs. 8 lb for the 80 sq ft). It also ships taller (50 in vs. 45 in) and weighs slightly more (83 lb vs. 73 lb). Choose the 100 sq ft for larger pools or when maximum Quad D.E. capacity is the priority.
How much D.E. is needed and how is it added?
The Quad D.E. 100 sq ft requires 10 lb of D.E. powder at startup and after each cleaning. Add D.E. through the skimmer while the pump is running — it flows through the plumbing and coats the cartridge elements. Always use pool-grade diatomaceous earth.
