I have a forty gallon Discus tank and I use RO-DI water in it. It is a planted tank so I just skim the surface of the substrate going deeper will damage the roots. Also I do 25% water change every other day due to the finicky nature of Discus. Most other tank are every other week except a goldfish tank they are a very dirty fish and require more frequent changes. Just my opinion.
