I raised a group of juvenile Discus approx quarter size, over a sand bottom tank and changed water 50 percent, three times a week and vaccumed the sand each time to remove waste laying on top.
In hindsight,, I should have raised the young Discus in bare bottom tank until they were at least six months old. Would have been much easier to see and remove waste and smaller tank for juveniles would have been easier with respect to water changes. My tank was 80 gallons and was also inhabited by a pair of german blue rams,approx eight sterbai cory's,and five or six Kuhlii loaches.
After a year,I performed once a week water change of 50 percent and vaccumed the bottom which by this time, I had switched from sand to gravel.
Juvenile Discus do much /most of their growing in first six months and require several (at least three) small feedings per day to achieve good growth.
It is the several small feedings per day that give rise to the need for frequent water changes to help keep water quality at optimum condition and cleaning the bottom,, whether it be bare bottom, or otherwise, is also needed for same reason. you do not want food or poop laying about in the tank .
