OK so I got my RODI in yesterday and set up a water station in my garage. Other than changing the RODI filters what kind of maintanence do you do on your storage containers? I am using an 18g rubbermaid with a float valve. How often should I clean the storage container. I know in an ideal world with the rodi water and no contaminates I shouldn't have to do it very often. I would like to hear some input. Also should I have a powerhead in my freshwater to keep the water moving?
