If t-ing off the return doesn't work you could look into a peristaltic pump. Even used ones are quite expensive though. One benefit of a peristaltic pump is that like the aqualifter you can pull water through the reactor rather than pushing, so as an added bonus the reactor is not pressurized. Peristaltic pumps are highly consistent in the level of flow and there are various types of controls for them.
I am currently using an aqualifter and like you am having the same problem with the cheap plastic gate valve on the line. Eventually I will probably get fed up and get a peristaltic pump.
