[FONT=Arial,Helvetica]The Generator[/FONT]
[FONT=Arial,Helvetica]The CO2 generator is simply made from a 2 litre plastic soft-drink bottle. Drill a hole through the lid, force some airline tubing through the hole and seal both sides with silicone sealant. Ensure that this seal is airtight. Alternatively you can drill a hole through a rubber bung (bought from somewhere like Para), force a small-diameter rigid tube (perhaps from an undergravel filter uplift) through, and attach your airline to this. Depending on factors such as the carbonate hardness, number & type of plants, amount of surface agitation, number & size of fish, etc. a 2 litre generator should provide enough CO2 for an aquarium of ( 200 litres. For larger aquariums a larger generator or several generators connected together may be required to produce enough CO2.[/FONT]
according to this , a simple 2 litre of a carbonated soda can generate sufficient CO2 for aquarium plants. Does it apply to weed too?Do you think this will work for a small grow?
