When i now do water changes with my r/o filter, how much ro water do i use to tap water, 75% rougthly?

How about if i do 30 litres of r/o water and 10 litres of tap conditioned every time i do a water change?
 
it all depends on what your PH/KH is from tap and what you want it to be. With this in mind, you should be able to find the mix needed to get your water just right.
 
Its for my discus tank, i want the PH around 6.5, dont really know about the rest...:S
 
Trial and error. Start mixing in measure amounts and test until you hit 6.5, once you know the "recipe" it should be easy.
