Good evening Brehmdig,
Also one other thing I forgot to mention. I was talking to Doc at Gold hog a while ago about my highbankers running 12 pumps and he suggested the Razorback Matting as it works better in lower flow sluices such as highbankers. I have had good success with the razorback and the scrubber, but I was running a 2200gph pump also. You may want to change the scrubber to razorback but ask around and see what other folks are doing. Doc sent me some of the new Bedrock mat a few weeks ago, but I haven't had a chance to get it installed and tried yet on my personal equipment so I'm not sure how that works with lower flow rates ( I don't even know if the public can buy the Bedrock yet). I'd check the Gold Hog site and forums for a better answer from folks, but for the desert and my highbankers I've had good results with razorback in the sluice.I need to try like a 1600 gph or so with the razorback and bedrock and if it works that's what I'll be running in all my highbankers from this point out instead of a traditional riffle system with the lower flow pumps (1600-1800 gph range). In the higher flow units (2200 and up gph) I'll run the scrubber, razorback and bedrock so the gold has 3 different mats to drop into.
I hope this helps,
Thanks, Chris
