Choosing RO/DI Unit for Aquariums and Drinking Water

[chromakey]

Good Day:

I currently have a 8 Gallon Nuvo freshwater and 28 Gallon JBJ Nano Reef tank. I am also thinking of adding a large freshwater tank.

I am considering a RO/DI system for the aquariums and also for drinking water. I just wanted to get some input on what other aquarists have used for this scenario.

Thanks for your help,

Michael
