If you have tried different positions and angles. You may simply have to dial the pumps top speed back a bit. 2 6100s is alot of flow in a 90 and the currents created might simply never "slow" enough by the time it hits the sand bed after bounching off the glass or colliding with the opposite pump's flow

You could also try the suction housings off of a 6200 series pump which would somewhat widen the flow path a bit

Thanks I have the pumps turned aliitle so they blow more up than straight ahead and I have them turned all the way down .I will ask some of my local reefers and see if the have any of those suction things.

You could also trade someone who wants to upgrade, your 6100 transformers for 6000 transformers. The 6000 transformer will reduce your flow almost in half.
