Hey guys. I was wondering if it would be worth my time making two DIY CO2 kits. This would be for my 40 gallon tank. I have been doing a lot of reading and it looks to me that CO2 really needs to be in the water for a bit before it diffuses into in. Simply putting the hose in the bottom of the tank and letting the CO2 gas rise to the surface wouldn't seem to make much of a difference. Would putting an airstone on the end of the tube help matters any? What about a diffuser? Could I put one of those on the end of the tubing? I have also read that you can put the tube under the filter intake. This would allow the filter to "suck" up the CO2 and churn it up inside the impeller. Of course then you run the risk of cavitation...
Or should I simply buy two of the Hagen CO2 kits. They are only around $20 each. I may spend that in materials building the DIY kits.
