I put hose bibs on the bottom end of the tank or buckets. Hook a piece of garden hose on it and run bout 2 ft to the sump pump. Turn the dial and 20 gal drains in bout 3-5 mins. Since I am doing 5 gal buckets this time around then skeets process sounds most efficient to me. One extra bucket is all you need, replace one plant into new bucket, clean the old one then put next plant in it while you clean next one....and so on. Even though buckets only have a few gallons in them, I will still put a ball valve on to drain the water first, then switch and clean. I will be posting parts and pics prob tonight as I put them together.
