Researching Discus can be a little confusing at times. I have read so many articles and websites that its not even funny. There are many confusing issues but the most difficult to understand is frequency of water changes. Some say everyday, others only weekly and some in between. Who do you believe? Once a day sounds like a little too much work considering I only come home around 6:30pm, eat supper and try to keep my wife happy :-*. I could handle every 2 or 3 days however. Next is how much water to change every 2-3 days, 10%, 20%, 30% or 100% every week. Another issue is water prepartation! I know that it is very important but how far do you go. I was hoping to get a python no spill changed so I can drain and fill my tank easily but maybe I shouldnt just fill the tank directly from the tap. Others say it is ok, some not. Discusaquarium, what are your thoughts? I did read your website and really like it. You actually got me started into Discus. I would like the best for my fish.
