Aquarium Changes during Water Change

During the water change, I removed the Jungle Lab's CO2 Fizz Factory in preparation for the placement for my *homemade* CO2 injector. The parts that I have purchased and used so far include:

• One CO2 Glass Diffuser purchased from Drs. Foster Smith
  
  
• Approx. six feet of Airline Tubing purchased from Drs. Foster Smith
  
  
• One Hagen 2-Way Ultra Gang Valve purchased from Fish Tails in Rainbow City
  
  
• One Hagen Plastic Check Valve purchased from Drs. Foster Smith
  
  
• One Plastic Needle Valve purchased from Gadsden Industrial Distributors
  
  
• Two Joiner Airline Fittings purchased from Drs. Foster Smith
  
  
• One Aquafina 1-liter bottle
  
  
• One small needle valve given to me by Fish Tails
  
  
• And finally, the Airline Connector and CO2 Reaction Chamber from the aforementioned CO2 Fizz Factory by Jungle Labs.
  
  

I'm waiting on silicon to cure on the joiner airline fittings that are now *installed* into the cap of the Aquafina bottle. The silicon should be cured sometime Monday afternoon, and when I get home from our family's Memorial Day celebration, I will be assembling and testing my homemade CO2 injector. I also plan to take some pictures and get some testing done as to the efficiency of the CO2 reservoir and the approximate pH changes.
