I have been making some calls today getting prices for a CO2 system.
So far I have found 10lb bottles for $90 and 20lb bottles for $120 - a
regulator from a home brew supply for $59 and I have yet to find a needle valve.
Is a 20lb bottle considered to big for a 125g aquarium?
I was hoping to find out if these prices are about avg. or if I should continue to look?
