Connor, you are in good hands here if you follow the guys advise, keep in mind any tank that has discus in it is a discus tank, everything else is secondary. Requires patients and a lot of work(maintenance). You got a great start here with all the advice, specially with fish-less cycle. I just helped a friend go trough it with Dr. Tim's one and only nitrifying bacteria, and it does work if you want to take that route when you are ready.
