The sound was definitely in the back. I hard plumbed the system using PVC over the weekend and added two ball valves to control the water flow.....The water now remains level in the back of the overflow (its not getting "sucked dry" anymore). I will prbably add another smaller pump to the system to increase the water flow inside the tank as I add more live rck, and will be able to adjust the ball valves accordingly to match the increased inflows. The fish store thinks that the pump and overflow were mismatched...... |
