If you could - re: circulation

Don't forget to add the $300 worth of plumbing/drilling and chiropractor sessions (for the twisting and bending you'll need to do installing all that stuff) to the CL install. This pretty much makes it a wash.

I priced the two options out myself when I was building my tank and went the Tunze route mainly because of the greater flexibility provided by the Multicontroller over the OM - night mode/feed mode/surging/pulsing/etc. versus switching back & forth.
