[QUOTE="WalnLiz, post: 103051, member: 147"] Good question troy and it can have a couple of answers. If the sloped expanded is directly on a carpet or woven matting then the water pressure should be adjusted to have approx half the expanded covered with gravel/ ironstone and the lower half should have the carpet/ matting exposed. Depends very much on your set up as by running no matting under the expanded it will give you a far better tolerance with water flows, and will be less critical with the amount of ironstone which needs to be displaced. Remember that no matting under the top expanded will require a rifle arrangement after the expanded to hold up the gold. Lazy "L" riffles require about the same gaps for gravel/ironstone as expanded mesh. Cheers Wal. [/QUOTE]
