Growonix DI-Resin Cartridge - DI-CART-2520 Disc Filters 3" body fits sump mountsGrowoniX DI Resin Cartridge for Near Zero PPM RO Water Reverse osmosis gets you most of the way to clean water, but a membrane alone usually leaves a few PPM of dissolved solids behind. This mixed bed deionization resin cartridge is the polishing stage that finishes the job, swapping out the remaining ions until the meter reads at or near 0 PPM. It runs as the final filter after the RO membrane, sized at 2. 5" x 20" to fit GrowoniX standard housing
