I was wanting some advice on what would be the "correct" stream setup for my 75 gallon mix tank. By mix I mean I have almost all types of corals in it, however they do tend to be confined to specific areas. My aquascaping is two hills with a valley in the middle of the tank. The sps are in the valley to right side, while the clams and softies are to the left side of the tank. I am wanting to increase my waterflow, to help with SPS growth, but I have no idea what would be appropriate for my size tank. Placement suggestions, quantities, controllers, etc... would all be appreciated. By the way, I do have about a 1-2 inch sandbed in the tank. Thanks.
