Keep in mind that every turn the water takes as it returns to your aquarium increases head and reduces flow. Keep tight turns to a minimum. A good rule of thumb if using 1/2" to 1" I.D. tubing is to add one to two feet of head for every 90 degree elbow or tee on the return side of the pump. The smaller the diameter of the tubing, the MORE head you should add.

If you reduce the diameter of the return line at any point, add a number of head-feet to your calculation equal to the percentage of reduction. If, for example, youve calculated a head pressure of ten feet in a 1" tube and you then decrease the diameter of the tube to 3/4", add 25% or

If however the pump must overcome the pressure of water pushing back from a return line below the surface, you must add some more feet of head to your calculation. For each return, add one feet of head for every foot the return point is located below the water and then add these together. If the return is more than two feet below the waters surface, make that two feet of head for every foot below the surface of your aquarium.

Add all your head variables together to det
