I agree, more is better but too much and you'll create a whirlpool effect. Your filter will turn over about 1000ltrs an hour which is pretty good. Gravereaper is also right, as i mentioned, on the hose trimming, but try it out first and see what the flow is like. It's better to remove hose than try to add it!!!
