Back before Marineland decided to outsource manufacturing of their Maxi Jet pumps, they were an industry standard. The new "Chinese" Maxi-Jets are a piece of crap....I would never buy one. Fortunately the original Italian company is still making and selling the original pump, but now under the name of Cobalt. I'd look at putting a Cobalt MJ900 on there with a valve to throltle back the pump. You could probably get away with a Cobalt MJ600 as well....but they are about the same cost, with sometimes the 600 costing more than the 900....go figure.
