RO/DI Filter for Aquarium and Faucet

[scherzo]

I bought the Vertex RO only unit from J&L and then bought a single DI canister with resin.

Cost me about $150 all together. You would have to get a storage tank but I think you can just get those at Home Depot. You would just have to have a T connector after the RO unit and one tube would go to your storage tank and the other would go to the DI cartridge.
