DIY CO2 Questions

[JDogg]

ok i will be attempting to build a CO2 reactor like the one described by tong HERE

i have some questions though

1. what kind of check valve, one like the one my on my air pump line?

2. any special type of air tube, or again like the air tube on my air line?

3. any special type of yeast?

4. will it be enough for my lightly planted 75 gallon?

1. yes

2. I use the silicone tubing

3. Fleishmans Dry Yeast

4. 1 2 Litre will not be enough. I have 2-2 Litre bottles on my 55G with a "T" connector to connect the 2 Litres together then 1 line going to the tank.

With a 75G you might be better off with presurized system, its expensive but you can use the DIY and just put your pressurized system together 1 piece at a time like I'm doing.
