Dave's High Pressure CO2 System
On the APD, it seems like at least once or twice a week, we have questions
or discussions on CO2 systems. I'd like to add my 2 cents. For a long time,
I've entertained the idea of upgrading my yeast system to a compressed CO2
cylinder. But I always backed off because of the price and because I
really didn't have a clear understanding of how they worked. I'm also
majorly DIY challenged. Then I got on the APD and was exposed to a wealth
of information about CO2 systems and everything else associated with
aquatic plants. That's how I found out about Dave Gomberg's high pressure
CO2 system described at www.wcf.com/co2iron. After reading the information
at Dave's website, I finally had a clear description of what all the
components are, how they work and how to assemble it. Not only that but
the price($70 without a cylinder) was far better than anything else I
had seen advertised. The web site also gives advise on how and where to
buy a cylinder. Since I finally understood how it all works, I decided to
go with Dave's system. I ended up buying a full 10LB cylinder at a fire
extinguisher company for $70. In Colorado Springs, by far, they had the
best combination of price, range of cylinder sizes, service and knowledge.
So, by the time, I got everything I needed, I had invested $143 with tax
and shipping included. While I was assembling the Eheim diffuser, the
small sintered glass disk broke. I don't know whether it was defective
or just a freak accident. So, I contacted Dave by email and told him
about the problem. Dave immediately arranged to have a replacement disk
mailed to me at no cost to me. Within a few days, I received it and
finished the assembly of the CO2 system(BTW, assembly was very easy
even for a totally DIY challenged guy like me). I now have a
steady stream of very tiny CO2 bubbles. The flow is consistent and easy to
adjust. I expect my 10LB cylinder to last about 10 months. My PH is
normally 7.6. With Dave's CO2 system, I'm now running at 6.8 in the
daytime. My plants are happy.
I haven't had the system up and running for a long period of time so I
really can't comment on the system for the long term. But so far, I'm
impressed and very happy with the combination of price, service and
knowledge resources.
