I would like to install a SWG, but I have a stainless steel DE filter. In doing some research online, it sounds like there are certain stainless steel filters that are compatible with salt and others that are not. "Newer" Pentair models appear to be ones that are incompatible. My filter is a Purex Triton (Pentair?) Nautilus Plus NSP and I have no idea whether it is considered newer or older.
Any insight into this issue would be greatly appreciated. Thanks in advance!
