I purchased a Clean and Clear RP100(160354) last year.
The filter works great but I find that the cartridge has to be cleaned often. Looking at your site it looks like I can upgrade the size of the filter to a 150 or 200 without changing the main body. Just change the top housing, cartridge and cartridge housing. Is this possible? And if so what are the exact parts I would need and available? Thank you very much for your help.
