I'm finally able to put in my RO
unit in my new place. I am putting in a small RO
unit and I am trying to figure out if a 3 stage or a 6 stage filtration RO
unit would be more beneficial for my tank. Any ideas? What do you use for RO
My tank is a 34 gallon saltwater with fish and corals (both soft and hard) as well as snails and shrimp!
