Its still almost 40 canadian :| I thought airstones were not very good a diffusing co2, mabye i was wrong. Well anyways, if i did use an airstone, I dont undersatnd what pusher the co2 out of the air stone. Now, i just want to confirm that i understand how to do the co2.
1 2 liter bottle with hole drilled in lid (not sure which size?)
force airline tubing into the hole and seal with glue
run that airline into the another bottle to act as a gas seperator but do you run that line into the water in the gas seperator?
Run another airline through a hole in the gas seprator lid to the diffuser. (again is this line supposed to reach into the water?)
What is the recipe for the c02 solution?
