Byron, if it comes down to the water current, I'm going aquaclear. I fill the water up to the top so the water coming from the hob filter doesn't produce any kind of strong current in the water. Not to mention the tank is 28" in height, the water from the filter isn't causing any disruption in the stress level of the tank.
Abbey, I originally had a 75G with the AC 110 and a 45G tank with the AC 70, which housed all my cichlids. I then purchased the 160G to combine the 2 communities and that tank came with the 2 fluvals. So while I was trying to sell the other 2 tanks, I kept their filters running on the big tank... just made sense to use them if I had them even though it may not seem necessary. But now that I'm selling the other 2 tanks, I want to keep that level of filtration but I don't want to spend a lot of money if I don't have to. Also, I was once told that you want to have 6X the amount of total gallons in the tank being filtered per hour. So for example, my 160G should have a total of 960gph going through all my filters. The fluval does 340 each, totaling 680 for the 2. The AC 110 does an additional 500 (allegedly), which together is 1180....should be enough. I've also heard just have double the tank's capacity in filtration capability. The fluval is for 100G max and the AC 110 is for 110G max. I don't know which recommendation is the right one but I'd side with safe rather then sorry with a tank full of dead fish...
