Aquarium Advice Apprentice
I'm considering buying a RO DI filter for my fish and I've been shopping around, but I'm not sure if I want one with a storage tank or not. Is it necessary to purchase a tank along with the filter, and what is the advantage of having one? My water has never gone out and I doubt it will unless a hurricane comes or something, so I don't understand the reason for storing up gallons of water.
