DIY CO2 Reactor Diagram

I have put a diagram of my DIY CO2 reactor on the AQUARIUM page of my
website(URL below). I'm using an Eheim to suck water into the reactor;CO2
comes from a 20lb cylindar. Flow regulation is manual via needle valve(not
the best way!). I plan to add a Sandpoint Controller soon. The plastic
Graduated cylindar can be gotten from any lab supply house. For media I'm
using the hollow ceramic bodies sold to fill cannister filters(serves to slow
CO2 ascent)
