We are considered the leader when it comes to Co2 equipment...All 30,000 gallons of our growing facility is injected with Co2.   All of the equipment  has been invented or fabricated by us. 

Co2 injection in an aquarium need not be complicated or problematic when done correctly.  If you have any questions, call us.  We would rather help "before" you have problems.

One of the biggest problems with Co2 systems is the regulator.  Most on the market are made in China and are very poorly built.  Problems include very inconsistant "bubble counts" and very short life span. Most regulators on the market have only a 6 month warranty...

Check out our exclusive: AquariumPlants.com's own "Electronic Co2 Regulator". It is fully electronic and has no needle valve and no bubble counter.  It also has a 3 year warranty!!!

"THE BEST" Check Valve (medical grade)
"THE BEST" Check Valve (medical grade)
"THE BEST" Check Valve (medical grade)(.017 psi CRP) 
After years of experience with Co2 systems, we finally discovered why consistant "bubble counts" are, most of the time, impossible. Here's why:  ALL checkvalves, even expensive ones, have a "high crp pressure" or "crack pressure" rating (the pressure at which they actually release) and/or a very inconsistant "crp" pressurre" rating.  We actually took a "caliper" and measured the Co2 tubing at different times and what we found is this: The tubing is actually a "long balloon"... When pressure builds in the tubing (because of a high crp rating of the CV) Co2 is "stored up" in the tubing, until the CV opens.  Then it releases, then it build up again, and more or less "cycles".  What you experience is a very inconsistant bubble count. This Checkvalve is "medical grade" (imported from Germany) and the best CV available.
