I started asking about filters in my pool-build thread, but will continue here as this is equipment related:
JasonLion offered the following when I asked about upgrading from the Pentair FNS-Plus-60 to the Quad-DE-100 filter:
I believe this will increase efficiency, lengthen times between cleans, lower pressues, etc. But a few questions:Originally Posted by JasonLion
How does this filter differ from standard DE filters? Seems instead of a mesh grid there is a pleated-material (cartrifge looking) like cylinder inside. I'm sure this is how the extra area is achieved. Is this a hybrid between a cartridge filter and a DE filter? Will the 'cartridges' the DE sits on last as long as the typical DE grid? They do not look like they will be able to be TSP/acid washed as a DE would typically be washed. Will they get build-up like the standard DE grids and if so -- how are they cleaned -- or are they just replaced....
I'll have a seperation tank for backwashing -- I assume it will work the same way...? (other than having more DE to seperate - 10 lbs)
I'd love to hear from anybody who has one of these. I trust JasonLion's opinion -- just would love to hear from somebody who has had to live with one (and clean it).
