Has anyone add a sand filter in series and infront of Intex 54611EG Krystal Clear Saltwater System and Filter Pump?
My reason is that a filter cartridge doesn't last more than 2 weeks on my pool. 7 of these will cost the same as a 14 in Krystal Clear™ Sand Filter Pump, $129 at wal. It should arrive this weekend.

The trick is to disable the pump but keeping the CELL running!
I'd like to feeding the water from the sand filter straight into the cell unit.
I don't mind opening it to make some changes and will try it if you have a bright and logical idea. Ths!
