Hello.

I just bought a refillable DI color change Resin Cartridge replacement for my RO unit. This is the first time I have bought the refillable canister with the separate media. There is a white sponge inside the empty canister. I am trying to determine where does it go. I assume I put the DI media in the filter, and the sponge on the bottom and then close it up. Just wanted to be sure.

Also, do I need to rinse the media or anything before I put it in the cannister? I assume not but thought I should ask.

Any advice would be appreciated. The place I bought it from is closed today and I really need to do a big water change this weekend.

The sponge is usually placed between the removable cap and the media.

You should flush new DI resin before using the water. 3 bed volumes (3 times the amount of water that would fit in a DI cartridge) should be enough.

Make sure you pack the resin in the cartridge as tightly as possible.
