The NU Aqua 4 Stage RODI System is a professional grade deionization system we have designed to work for aquariums, hydroponics, homebrewers, laboratories, or any situation that requires consistent high-quality water. This system includes both a faucet diverter attachment, as well as a hose attachment which enables you to use this system in any application you need. 

Featuring high-quality fittings that ensure a leak-free experience, this system also comes assembled and installation can be done in just a few minutes. Color-coded tubing makes this process a breeze.
