Oh I was guessing on the Mag 12 thing, It just seems like a lot of back pressure.. Just curius, do you have the skimmer on a 3/4 return to the sump?

You can use the Maxi Jet venturi on a Mag Drive pump. Premium Aquatics sells them for less than $5.00. You'll have to add a couple of PVC fittings to get a tight fit though. Or...you can get a Kent venturi in 1/2" or 3/4" for less than $20.00. Or...see my posts in the DIY forum on a DIY venturi. It actually worked quite well. I agree with Timbo though that you need a pretty strong pump for that size skimmer. If you DIY an air intake into the pump inlet, you should also plumb in a regeneration line which will recirculate some of the air/water mix through the impeller...you'll get finer bubbles that way. IMO, the venturi on the pressure side of the pump is the best way to go. It will require less adjustment and will give you better flow. My DIY venturi is made from readily available parts from Lowes and requires about 20 minutes to assemble with minimal mods to the parts. I'll try to dig up the post and edit it in here for you. EDIT: Here it is:
