Plymouth, MA, 1988 IG vinyl pool, 25K gal. Pentair Superflo VS (new 2014), 36 sq ft Nautilus DE filter and we have a Tiger Shark cleaning robot. Pipes are 1.5 inches. 2 skimmers and 4 returns. There are no waterfalls, heaters, spas or any type of special features.
We are looking at purchasing a new filter. Our current DE filter may be origianl equipment and I have had to resew the seems on one of the filter grids. I realize I could replace the grids but it seems wiser to invest in a new filter rather than spend money on this old one.
My question is, are there filters that work better at the slower speeds the pump will be running. I have read that sand filters offer more resistence and therefore you need to run at higher speeds. I also read that cartridge filters offer the least rsistence.
We like the fact the DE filters can filter out finer particles.
The salesman at our pool store is trying to sell us a Pentair Sand Dollar Clearpro Technology sand filter.
Any reccomendations? Any expierence with the Sand Dollar Clearpro? Would we have to backwash the Sand Dollar every week?
