For some fish and plants RO is recommended (such as some cichlids and discus) but for most fish I think dechlorinated tapwater is fine. RO/DI water tends to be pretty unstable. Just like you have to be really careful picking corals and fish that like similiar temps, and parameters, FW plants and fish require careful consideration re: temp. water hardness and ph.
