In that case you can do a planted tank to take care of the ammonia. Live plants actually prefer to consume ammonia to get nitrogen.
The idea of a refugium is still valid if you have fish that eat plants. Just like in marine tanks with macro algae.
But a refugium is just a protected area where the plants can grow and thrive free of the fish. So all you would need for instance is just a partition so the tank has a small plant area and a larger fish area. Not the expensive external refugiums/sump available commercially.
