I ran the cascade 1000 on my 55 alone until my fish grew then I added more filtration. If your stock isnt insane it should be plenty.
If that penguin the one where you can adjust the intake volume with the little lever up on the intake tube? if so I would just open that up and run it so it decreases the suction from the bottom inlet.
