Its difficult to say. test water weekly and if your nitrates go above 40 then you will needd to do bigger or more frequent water changes. You may find yourself doing 3 large water changes a week
If your ammonia or nitrite go above 0 then you will need more filtration unless something has gone wrong with your filter
When I had a large plec in my 55 gallon with my oscar it was essential to do at least 3 changes a week, and even with good filtration the nitrates would be a continual issue.
I think in this case 3 nice sized changes a week are pretty essential.
