If you could do anything with the tank using the equipment listed what would you do?
You can move all the fish out and change everything except the filter, tank dimensions and heater.

I have a large amount of drift wood soaking too.

I'd get rid of all fake plants, replacing with anubias at the very least; and some vallis

Then I'd add 3 more discus, and bulk up the cardinal shoal.

The thing is this is the discus that killed his other three tankmates.

I'm thinking that I might go full blown planted and add 80 more neons and two more schools of tetras of barbs.

Definitely add a few more discus

Already tried that.

I would build up your school of cardinals or neons

 

[FMA4ME]

Add at least 5 more adult Discus, same size.

Sounds like you may be looking to abandon discus, which is a reasonable option if its not doing it for you; in which case I'd do the large shoal of cardinals like the above poster mentioned.

Could create a stunning planted set-up for sure

Bulk up the cardinals add bog wood and six Bolivian rams.

I think that's what I'll do as well as try adding two more small species that school tighter that the cardinals.

I think it's either full blown planted or grow out tank for sure. I think I might have to use this last discus as a feeder if he kills one more cardinal.

Isn't six a few too many given the footprint?
