I am in the process of setting up a reef tank (a few months in and have 2 fish and various corals) and I have a few questions about topping off the tank.
-I have heard purified water is the second best option behind reverse osmosis water, is this true?
-Second, if I want to start using RO water what are my options? Is the best option simply to purchase an RO fileter online? I have not had any luck finding RO water at any local grocery stores around here (I live in Chicago).
Thanks!
