EcoCart Replacement Loose, Pre-measured DI Resin Refill
This is a replacement loose, pre-measured DI resin for the HydroSphere EcoCart multi-stage system.
This is just enough DI resin to fill the EcoCart's DI canister.
You can also purchase the complete DI cartridge already full of DI resin or a cubic foot of loose DI resin and refill the canister yourself. The replacement carbon/sediment filter and RO membrane are also available. See the related items below.
