Recently had to take a closer look at my filter ( I have a Sta-Rite S8M500 -- 20k gal pool) and in doing so I realized I have to replace my cartridge next summer. Looking at the prices, they cost a big chunk of money ($500 for the set). That's when I came across a star rite DE filter that has a cartridge looking filter (but it's still DE !!). It looks like it has all the benefits of both DE and Cartridge worlds. I'm talking about a S7MD60 or 72. So I started wondering, is there any way of converting my cartridge filter to DE? Has anyone done it? Any pros or cons of this? Any thoughts? Thanks.
I came across the following that makes me think it might be possible. The cost of these parts + a new multi port valve would come around ~$500.
