A week into this course, I can say that it's really much more than just building a reactor. It's about acrylic fabrication techniques; I'm learning alot. i would recommend anyone taking this course if it's offered again.

One initial thing is the difference between cast and extruded acrylic. Most store-bought acrylic is extruded, especially tubes. Cast is much more expensive, but much stronger. The teacher of this course recommends only using cast acrylic for aquariums, reactors, etc. Any application which will withstand any water pressure.
