Good point shuks,
I kept thinking about it.
I'll describe how I am dissolving the CO2 in my tank, please tell me how I can improve on my setup.
I made one of those DIY CO2 reactors
for one of the 3 CO2 yeast solutions.
The other 2 just feed into a glass diffuser bell. But one of them is situated right beneath my filter's intake tube, so all the bubbles get churned up by the filter's motor.
Let me know if you have some ideas on how to improve on this set up.
