Cool...
I'm really impressed by the fact that you have had so many spawns Arthur...Your Heckels definetly like what you do in this tank.
I hope you get the chance to seperate a pair to try to breed them...

Harry,
Great question and one that will bring upon many debates... actually it has already and if you search here you will find many reasons why or why not to change as much water for wild discus.
Some research and hobbyist experience has shown, or some believe that too much water changes can lead to the deadly whirling disease. Many experienced wild keepers have noted that they change water less frequently and at a lesser % than domestic keepers and their success rates have been higher and the whirling has been less. Others will argue discus are discus and these fish were pulled from a system of millions of gallons that is turned over at an unbelievable rate.
The true questions comes from your water, your conditions and your experience. I personally believe that if you are aging water and the params are stable then there is no such thing as too many water changes. That being said, as an owner of wild discus, I change my water typically twice a week, here and there a third time. Usually about 75% of my 75 gallon tank with a 29 gallon sump. I have found this routine to work well for me and my fish.
Hope this helps.
