Too much current? - Sand blowing

[My closed loop is blowing the sand away from the corners of my tank. Is this just a matter of repositioning the locline over and over again until the sand no longer blows? What's the best method to get good current, but not blow your sand all over? :taz:

Thanks!]
 
[Well I think I may have fixed the problem by pointing the loclines to the opposite sides of the tank. ???]
 
[Yes, you'll have to find the perfect spot to avoid sand movement. I have mine moving somewhat, but not enough to cause a lot of problems.]
