BK, Suphew is not telling you that you are doing it wrong he is speaking from his own experiance of keeping discus and is trying to help you not spend all that money on some nice fish only to lose them from rushing things.
In my Opinion, if you arew going to ask the questions but are not prepared to take on board some of the answers, I would suggest not asking the questions.
Majority of the users here have no commercial interest in the hobby and are speaking from experiance, so it is usually good to respect what they have to say, and as with most hobbies what works for some, won't for others, but you don't know if you write it off before giving it a shot.
