Over the years people have gotten better and better at keeping discus and it has to do with obeying their need for soft water, and moderate to low pH, high oxygenation and well-doing live plants. That can be insured with the use of fluorite for a substrate. Adding tannins artificially or by using real driftwood, is also helpful. I think one of the greatest keys is high aeration or at least surface agitation.
