Default DIY Co2

Thanks everyone for the help so far. I went a step further with my tank today and installed a DIY C02 System. Here's what I did:



#1 Gathered the supplies. As you can see I used a 2L coke bottle, silicone air lines, silicone aquarium sealant, a drill, one way valve, I also used pliers, sissors, measuring cups and spoons, yeast, sugar and water.

#2 I made a hole in the top of the coke bottle a little smaller than the tubing. I cut a short section of tubing, and pulled it through the bottle cap with a pair of pliers. On the outside end of this section i put a one way valve.



#3 I sealed the area where the tubing passes through the bottle cap with the silicone sealant. While waiting for that to dry I mixed my Co2 agents by combining 1/2 tsp. yeast, 1 3/4 cups sugar, and 6 cups of lukewarm water. I then placed a piece of plastic wrap over the end and shook the mixture.



#4 While waiting longer, I cut a section of tubing and tied it to the intake of a canister filter using fishing line. I placed the open end at the bottom of the intake grill as you can sort of see here.



#5 I then attached the mixture in the bottle to one side of the one way valve and the output to the other. and Voila!



And here's a closer view of the connection to the bottle.



I'm now waiting and monitoring my mixture and Ph levels. I'll let everyone know how my experiment works out!
