Yup - already put some icecap 4k's in to start with. I was planning on putting 4-6 MP40s along the back wall of the tank.Removing the Locline won't improve the flow. If your fine with that turnover than it shouldn't be an issue. I'll rather have more flow than too little. I can always tune/turn it down. If you have enough powerheads in the main display then it should be fine. A tank that big needs gyres or mp60s. Don't use the mp40s. It won't reach from side to side.
