Just a week ago I set up and planted my first aquascape. The tank is 30cm square and at the moment is plants only. When I first filled the tank I used tap water without any dechlorinator as I did not have any at the time. The tank has been sitting since last Monday so I assume that it would benefit from a water change. I now have a bottle of Seachem Prime so I can add that to the any tap water I use. But what I would like to know is can I use RO water? I have some in store for my reef tank. If I can what additive products I would need to add to the RO water? Also, can rainwater from my garden water butt be used in aquascapes?
