Flushing RODI units

[goochesfish]

I just learned from air water and ice where I got my reef keeper from that the system needs to be flushed 1 minute for each day of non use. I make 50 gallons once a month. That means I would flush for 30 minutes? I live in often drought riddled CA. Does anyone really flush a minute for each day they don't use their RODI?

I flush for 1 minute before each use regardless of how long it has been sitting idle.
