Re: Pressurized CO2
I recently took the lazy but more expensive route, by purchasing everything from an online aquarium supply place. I spent a total of $400 for a 5lb bottle, regulator, solenoid valve, bubble counter, and pH controller.
I know I could have gotten everything much cheaper buying it as mentioned by Tom, but I was unsure of what to buy seperately, so I went with the complete marked up package where someone else had already done all the thinking as far as which devices will connect up to and work with others.
Just thought I'd provide an upper end to the pricing for you so that you would have a good range to work with.
The up side is that now I am somewhat familiar with the devices and now know what to look for should I ever need to buy another system, and would feel comfortable buying the parts cheaper individually.
