Your carbon and zeolite/carbon mixes are worthless. You need more bio-media. Get rid of all that carbon and zeo-carb and get some scrubbies, ceramic rings, bio balls, etc.
Bro People say u have an overstocked tank I wonder what they will say about me lol I have a 125 gal with 1 9 inch RTC 1 8 inch rtc X TSN 2 Clown knifes 1 14 inch fire eel and 1 8 inch Irridescent shark lol Now that is an overstocked tank. BUt if u come to my house u would think I have no fish except the shark because they all hide during the day and come out at night. I had the same problem u did but i started doing water changes of 50% once a week and everything is fine now
A lot of good advice has been given, but the only real long term solution to your problem is going to be to reduce your stock. As those RTC's and pacus start getting huge, it's going to get even worse.
start getting huge lol dude they are already hugelol never had this problem with their other tanks well I know I'll get it done just got back from AA and they got me all situated more bio ceramics filter pads and cycle with a nice big water change i'll be fine I just got to mad at the fact of having amonia way to high and freaked
