Mag 3 (10.5 ft head pressure max @ 350 GPH)
MJ 1200 (5.75 ft head pressure max @ 295 GPH)
The Mag 3 is capable of almost twice the pressure as MJ 1200! The higher pressure means more force going through the spray injector and may cause you to have bigger bubbles. Dropping the force a bit will likely reduce the bubble size.
Also think about flow through the skimmer. Going down to a MJ 1200 will slow the flow through the skimmer (by about 18%) resulting in increased contact time with the water/bubbles. Smaller bubbles and increased contact should give you a dryer skimmate...I think.
