What is the best way to aerate the wort in my Chronical?

We currently have inline oxygenation kit for sale on our web site ( Oxygenation-Kit ) 

Then you have the choice of either using O2 (our preferred) or an aquarium pump with a filter.  If you use O2, you can get O2 tanks from Homedepot or similar home improvement store.

You will also need a Regulator Valve.  http://www.williamsbrewing.com/OXYGEN-REGULATOR-P700.aspx

OR

If you use an air pump, you can find them at any pet store.

Read up in the book YEAST by Chris White to get an idea of times and dissolved O2.
