I am looking for 10g or more of RO Water. I called our local fish store and she thought that I was nuts. Didn't know what I was talking about and told me to just put tap water in the fish tank and said it would be fine. Yea from what I was told from the friend I got my tank from he said absouletly do not put tap water in and said I needed RO Water. So, that is what I am looking for. Anybody around or half way near Keenesburg area can help a newbie out? THANK YOU!
