If it was mine, I'd be doing 40% every other day (or whatever kept nitrate low < 10ppm).
That said, that's what I do now with my 180 gal, and much smaller fish, in order to keep my nitrate levels < 5ppm.

Ah ok that’s certainly doable! If it comes down to it I can get a 120 in about 12 months but thanks for your input and advice Iv certainly taken it in to account

It is doable, but don't do it! The fish will be crammed in a little box! You will be doing every day-every other day water changes!

I Guess it’ll be a nuisance! I do take in what everyone says so an upgrade will definitely be coming when he gets to his larger stage

Exercise, stimulation and activity is important to your fish too. I've noticed Oscars in smaller tanks just hover in one place because there isn't room for anything else. Then the owners feel smug because they keep up with water changes and say "no problem!!"...its an environment, not just chemistry.

Totally agree. A point that's not always considered.
