Just making sure I get this right

I have a 90 gallon aquarium housing 2 adult oscars, and after much reading I have realized that I am under filtered. I am currently running an ac 110, an emperor 400 and a sponge filter. I know oscars are dirty fish, so I was thinking of getting another ac 110 from petsolutions for more mechanical filtration, and a sunsun/perfect canister loaded up with bio media. Does this sound like enough filtration?

I plan on ditching the emperor, I hate it haha

Why do you think your tank is under filtered? Don't believe everything you read. LOL!

The emperor on its own is rated for a 90gal. As long as you keep on top of water changes and regular maintenance you should be ok. If your parameters start getting a little off, then I would upgrade. On my 90 growout tank I have 150gal 3 stage filtration betwenn two filters and iv never had water quality issues, but I do 35% weekly water changes and keep the tanks super clean. (im a neat freak)

I'm doing 40-60% water changes every week, I have a tetra test kit that I check nitrates nitrites and ammonia, but I really don't trust it. are API master test kits a good kit?

All I know is that when I kept Oscars, I never ever had enough filtration. ever.. Or water changes for that matter!!

The API kits are great. They're pretty much the industry standard, and you see them everywhere.

Your tank doesn't sound under-filtered to me! But it can't hurt to add more, really.
