Diffusing CO2 in my 25gal
I dont have any fancy equipment for diffusing CO2 into my tank.
I'm using the DIY CO2 method.
There is a little point on the top of my wall filter (Dolphin F1200), where I can attach the tube of my DIY unit too. But it appears as if the CO2 just gets blown out of the filter along with the water. It seems like the CO2 then just goes almost straight to the surface and out the tank, and doesnt get diffused into the water. This is not a good way of diffusing the CO2 I'm guessing...
What Can I do? Is it okay if I attach a air-stone or sponge to the end of the DIY unit's tube and place it in the bottom of my tank?
