Lance's 225 gal tank

[Lance]

Here's the skimmer. It's a MR-3 with dual Becketts and powered by an Iwaki MD-70RLT pump. I haven't any experience with these skimmers but have been told they do a pretty good job. I hope they pull decent skimmate as this tank will have a pretty large bio-load with the large fish. Any MR owners out there? I could use a few tips as to proper water level, air adjustment etc.
