Complete newbie here, so sorry for the basic questions.
So I have a DEP51 DE filter which so far has done a reasonable job. Although I now believe the filters will have to be replace, cost wise $190 ish was the cheapest I could find for all 13. My drainage is also blocked, so I have to roll out a hose every time to backwash the system and now the water company is installing a meter. This got me thinking about cartridge filters which I believe might be the more economical option?
First of all, I have no idea of the physical size I would need, see my signature below for pool specs, any ideas? I was thinking of something along the lines of a Hayward C900, initially that looks like it would be able to handle my pool size? Or should I be looking at something completely different? I had never considered a cartridge filter but reading Pool School it seems like this might be the way to go?
Thanks for the help guys! Really appreciate it!
