I only have a 94L tank and wondered what is the best way to get RO water or water suitable for the tank, I've heard from people before tap water is fine if added de chloronator, although I've also heard not to use it, can I use bottled water and add salt that way or shall I just stick to purchasing it from fish stores? I don't think spending loads on a RO system is worth it for such a small tank, please help!?
