depending on how stocked a tank is I usually like for my filtration to turn the water over 10-12 times per hour at least. on the 150 I was talking about in my previous post I was filtering 1500 gallons per hour (exactly 10 x per hour) and that was when it still had a tendency to get cloudy. I added another 500 gallons per hour (2000 total) and that was when the tank stayed crystal clear all the time.
so all that being said, you're about 300 gallons per hour under 10x per hour so you may be slightly underfiltering depending on how much waste your africans are putting out. you might try adding a HOB (AC 110
) just to polish it off.
