I was a witness of a conversation in store between 'wanna-be-discus-keeper' and store employee. I guess (I have never kept them) it's possible to keep discus in tap water as long as it is clean when you are not going to breed them. Store employee was trying to sell this person some chemicals to bring pH down to 6, black water extracts and some 'nitrate absorbing material' while the same result could be achieved with simple RO water changes.
