I was just reading the DE vs. Sand filter thread. Great info; thanks. I am planning a 30-40K gal. pool/spa & wanted to maximize dirt filtering capacity (minimize backwash) due to lots of pets & even free range chickens which lose lots of feathers etc. Was interested in using the 3.2kw Intellitouch & pump.
Wondering if you can series a large 36" sand filter flowing into a Quad DE 100. Was thinking the sand would p/u the large stuff & the Quad DE would polish off the small stuff thus extending backwash/maintenance. Would that be too much pressure drop/electricity? If it is oversized for the flow rate it seems like the added pressure would not be too bad.
Any equipment advice for an ideal system would be appreciated! Need help figuring this all out!
