20 gallon RO storage tank.
So I am considering getting an RO unit for my apartment. The only place I can think of to set up a storage tank is on the bathroom counter or maybe under one of the sinks. I only need to use 5-10 gallons of water per week, so I figured a minimum of 20 gallons for storage. Anyone know of any 20 gallon, fish safe, preferably square or rectangular storage tanks that are affordable? Or where to look in town for them?
Also on a slightly different note, do RO or RODI storage tanks need circulation pumps in them?
