Head Ratings
Pump head measures the vertical distance a pump can effectively move water. As the height increases, water pressure decreases because the water must travel a longer distance. Measure the distance water will travel on your setup (e.g. the distance between your sump and aquarium) to determine the right Impulse™ for you.
