moving sand

[slant77]

I have a 6 foot 180 I have 6105 on the side panels pushed to the back wall. Each is pointing to the others side front corner. The issue I seem to have is blowing the sand away from the front center of the tank. They are 6 inches from the top and barley point down if at all and the ramp up is less than half. Also 1 6105 behind the rocks also mounted one side wall.

I can think of a few possible solutions.

1) Lower the voltage on the power supplies with the jumpers that were included, 18 or 12V.

2) Lower the pump and try a slight upward angle

3) Try the wide flow housing 6205.130. This will diffuse the flow more and reduce its reach.
