Intex saltwater with sand filter

[BigDave]

I think the Intex salt unit is combined with a cartridge filter. Maybe Both filters could be connected in series - maybe remove the cartridge.

You may be thinking of something like this:

INTEX Krystal Clear 1,200 GPH Cartridge Filter Pump & Saltwater System

That model cannot be used with another pump and filter. What you probably want is one of these two models:
