    De filter and segment

    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?

    Sounds like BS to me. Pentair describes it as being made of fibreglass reinforced polypropylene. That plastic is impervious to almost everything. But I looked up the Owner's Manual and did Ctrl+F for salt and got nothing. The word doesn't appear. If there's a problem using salt, you'd think there'd be a warning somewhere in the Owner's Manual, wouldn't you?

    Was this someone who told you a salesman of some sort?

    My friend that told me has a DE filter with no SWG and he said the label on his DE filter says for fresh water pools. I could call Pentair on Monday.

    Is your friend's filter tank stainless steel?

    If so, that's why that label is there.

    I don't think do, at least not on the outside. Just a light tan color on the outside

    When that equipment says for fresh water only. They're not talking about pool with normal swg's. They're not designed for ocean water pools. Swg level pools are still considered fresh water pools.

    That's what I was hoping, not a true saltwater pool. Thanks
