I have made a lot o research about keeping discus. Sure I will be reading more.
On the topic of WC, I had read a lot of contradictory information. Some say that you won't make it if you don't do 90% WC twice a day and other say that make 20% twice a month and their fish are great.
I was trying to find a number between the two different opinions. I see that a lot of people are a big fan of big WC, but what's you minimum recommendation for a tank that's stable and not overstocked?
About the process of aging water, I read that if the PH oscillation between tap water and 24h aged water isn't bigger than 0,2 there's no need for aging water. DO you agree with that?
