The importance of using Reverse Osmosis (RO) water for use in an aquarium cannot be over emphasised.
Reverse osmosis water is essentially free from chlorine, nitrates, phosphates and heavy metals and is an ideal base for making up salt solutions or for freshwater aquariums or replacement of evaporated loss.
Tap water is generally full of these pollutants and the effect on your aquarium can be quite severe depending on how bad the water is in your particular area.
