I thought about this a while ago. I think there is a simple solution to remove
any HCl from the CO2 that is going to your tank. Just bubble the CO2 through
a second chamber containing water with some sodium bicarbonate. As long
as the bubbles are fairly small, this will effectively scavenge the HCl.
Better yet, let someone else produce CO2 by the reaction of acid with
limestone, and just bring it home in a bottle. :)
