I’m just getting back into discus myself and am remembering how dirty the tank can get in just 24 hrs. I have a 75 gal tank with 6 sub adult discus. I use water aging barrel that holds 60 gallons. I would say I do 70 -80% water change every other day. Most of the time I just change water everyday. Their waste adds up fast and I don’t like seeing it on the sand bottom.
