Guys,
I have an older FNS60 filter on my pool and I'm pretty sure the grids are giving out as I'm spitting DE into the pool. Is the FNS Plus grid assemblies interchangeable with the FNS60? If not, other than the grids what should I replace when I crack it open - manifold, grids, etc??? I can get the entire preassembled manifold and grids for a good price at Amazon for the FNS Plus but I'm not sure they'll fit my FNS60. Please help.
Dave
