DIY CO2 Question

[Mattei]

Got all my materials for a diy Co2 system, gonna be using a plastic air diffuser, just wondering where is the best location for this in my 20H tank?

at the bottom so the bubbles have the longest travel possible in the water.

I second placing the diffuser at the bottom.

Also if you can get it near the filter intake that would be good too. The impeller chops the CO2 bubbles into a finer mist and they dissolve inside the filter.

I have my CO2 split into two lines, one to a place that is aesthetically pleasing to see bubbles rise and the other into the filter intake.

musicman is right. the bottom and by a intake so it can break it up even more.

okay I have it set up running a line down to the bottom of the tank underneath the intake. It sprays a few bubbles every so often and the intake sucks it up and chops them.
