Converting a maxi jet 1200 for pump on calcium reactor

I realize you already have the maxijet, but thought it worth mentioning I use an AquaClear powerhead (similar to maxijet) to feed my skimmer. The AquaClears have a lever at the intake side that allows you to regulate the output. Not sure it could be throttled down enough for your purpose, but would certainly keep the plumbing situation simpler, which is usually a good thing. Similar price as a maxijet, so not a huge investment if you can find one.
