Methods of DIY co2 diffusion.... Bring em on People!!!!
For all you bio chem peeps out there im sure you all know making the stuff(co2) is pretty easy... In fact I reckon more difficulty lies in getting the stuff dissovled in the water so that the plants can actually use it, which Im figuring is probably the reason behind the rediculously high ass load of costs to actually buy the proper equipement. But screw that right? for all my fellow students eating mi goreng, I dont think its gonna happen.
So having said this i think its about time the good ol DIY co2 diffuser rose to the spot light in an effort to gather as many methods/setups out there as possible. Having now seen numerous methods of DIY co2 diffusion im indecisive of the most effective method diffusion, whilst comprimising costs ect, to use for my latest 50 gal planted setup.
Ok so basically the main motive of this thread is to gather as many varieties of DIY C02 diffusion setups and to share any images or discussion about them, such as:
successes, failures, recommendations, refelections, design specifications, reasons why yours is tottaly sweet, and any other queries.
I will get the ball rolling...
My first co2 diffuser was in my 10 gal and consisted of a internal co2 gas resoviour which captured the co2 bubbles from the yeast reactor. It was bassically a upside down plastic container positioned underwater so that the co2 bubbles floated upward into it and displaced the water downwards. So the co2 stayed in the aquarium, instead of simply floating out, in an effort to increase contact duration. This sat next to the outlet stream of an eheim 2008 internal filter in an effort to increase the turbulence.
This was an ok method of co2 diffusion and did manage to create a rise in co2 levels, but not alot. Im sure there are much better ones.
One other question..
Im considering a canister for my new 50 gal. Im wondering what peoples experiences in using that as a co2 diffuser aswell is. Ie does it degrade the filter at all, etc... Anyone?
Bring em on!
