Is it ok to use a DE filter along with a SWG? I was planning to use a Pentair FNS DE filter along with a Hayward Aqua Rite SWG. Someone told me that this particular DE filter is for fresh water pools only. Is there a difference between a saltwater pool and a pool with a SWG? Am I ok with this setup?
