i have been doing alot of reasearch and learning alot about them, as i will be setting up a tank in the neer future...but the thing that i keep getting mixed answers on is the hardness req. i have talked to so of my friends that have discus and they have said that as long as it is stable it isn't so important...yet others tell me that my water is to hard in st. paul, mn and i need to soften it or they will die...i would like to resolve this so i know the truth for my fish...so the main q. is how important is the water hardness?
