There is a needle wheel power head out there made for this skimmer as an upgrade, I forget the brand but it does perform much better then the stock pump or even over the MJ1200 pump upgrade.
I always thought these skimmers were mediocre and let out a lot of micro bubbles into the tank IMO. If I needed another HOB small skimmer, I would look into the brands that utlize an overflow box and has the skimmer pump outside of the tank.
