I need help with setup of the intake and outflow line in my 75 gallon dutch style aquarium. I get almost no flow in my tank because it's heavily planted. What can I do to increase the flow and where should I put the intake and outflow? Currently I have Ehiem 2213 that outflows into an inline sterilizer then inline heater then through inline c02 injector. Then it flows out a bar at the bottom center of the back of the tank. The intake is in the very left back corner bottom.
