Diy CO2 - question about diffusion method
i've recently made a DIY yeast CO2 generator for my 10 gallon tank. For diffusion i used a combo of the diving bell and chopstick-stuck-in-the-airhose method -- i.e. used a chopstick at one end to produce the tiny bubbles, then stuck it under a shell(the diving bell).
I was hoping that the tiny bubbles would slowly accumulate under the bell, then slowly seep out the edges as individual bubbles as the bell filled up....but what's happening is that the bell burps out this one large bubblefrom time to time.
Is this the best way to go, or am i better off without the bell? I hear a powerhead can help spread/diffuse the bubbles but i only have an airstone-powered sponge filter.
