If you get them ask her to feed them when you are there, and ask her to test the pH. I have a friend who has discuss and even though our water comes from the same source his pH is lower because he uses an RO
system and peat moss . I know how you feel a couple of months ago when I got my pair of rams I was the same way but after reading some posts about people keeping those fish under similar conditions I decided to get them.
BTW: According to what I've read and been told a weekly 50% pWC
is a must with discuss.
