i have no experience with the 2000, but my 3000 is currently skimming very thick and dry foam...I need to wet it down a tad, but overall, its doing well...I really dont know how to comapre it to my G1x, its obviously a much bigger and stronger skimmer... as for dialing it in... not really much to do...I did the gate valve mod... also the washer mod for the venturi, I think others are looking to increase the airflow through the venturi through other mods.. but for me, I am happy with what I am getting right now.
