I have a jacuzzi pool filter for a 13,000 gal pool and spa. It uses cartidge filters, the largest sized TRi-clops filters. I have replaced them from time to time over the years, when needed. Now, I can't just buy the replacement filters, apparently. I have to buy them with a 'conversion kit'.

I need help in understanding what is involved with this step: installing the conversion kit. Anyone have any idea what is involved? Any web sites that I can access to see what needs to be done? I have kept rewashing my latest set of filters (there are three in a set) for two+ seasons - but now I need to do soemthing about this issue.

Thanks for any advice/help.
