water change-how often

[mitchar19]

I just recently upgraded my dicsus home to a 75 gallon, how often do I need to do water changes and how much? I have 6 juvi discus about 3 - 4 inches each and I feed them about 3-6 times a day.

If you're looking for maximum growth I would change 30-50% daily (that's what I do for my angelfish) and will be doing when my discus are in my 75.:)
