Go get a flow deflector from your lfs, its a little powerhead that rotates without any excess power going to it, it simulates the flow of the ocean and creates great water surface tension. Take the bioballs out and replace it with somel live rock rubble, those things will crank up your nitrates and are a pain to clean. I use the stock filter for about 2 weeks out of the month and then take it out, replace it the next month.
