Welcome to the forum and discus fish keeping Don .
Your water parameters are on the soft side wich is good for discus fish and pH of 7.8 although alkaline is not that bad either. The best PH is the stable one , and you can achieve it with regular Water changes and aging your water .
Just find a way to age and aerate the well water for 24 hours prior water change and you'll be good to go with discus .
Good luck with your new adventure Don and keep us posted with pics and Info's.
