recirculating sluice box

[tweeta_bear]

hello everyone. i have an a52 keen sluice that i turned it into a recirculation box. i was told that the proper angle is 1" per foot of fall. thats how i set it up. i was also told the 2200gph should flow threw it. im wondering if this is correct. i am from colorado and most of my material will be classified at 1/4" and its going to come from clear creek just outside of blackhawk. here is a pic of how i set it up.

1 inch to a foot is right.
You may still have to adjust,depends on water flow and material.
Make sure your material is damp or wet.
I set mine up with 1 inch to a foot,and then regulate the water flow.

I'm thinking you might need a little more water flow than that, I set my A51 up with a 2000gph pump and had to make the drop a lot more as the water flow wasn't what I thought it would be, so you may need more drop so the riffles will clear.

so add alittle more slope to offset the flow?
