That is sounding positive, I will ask around here. I've seen Discus but only at aquarium shops in tanks. I want to put them in a pond, outside. The temps should be fine but it is the PH I was worried about. Of course, they aren't as beautiful in a pond because you can't see them from the side. I found that with the Angel's I have in a pond. I just don't have room, or time, for an indoor tank right now. Outside, they will get rain water, which has a slightly lower PH, half of the year but I will need to top off with well water the other half. I'm going to start questioning the aquarium guys I know here and see what others have done. I just assumed it would not be healthy for them.
