Running co2 to two aquariums.
How can I run co2 to two aquariums. I will put a Microsoft paint sketch of where the tanks are situated. I was thinking about using a "T" splitter. But I don't know how I could monitor and adjust the amount of co2 between the tanks. I have a cheap plastic 4 way gang valve that I got at petco for air pumps but I feel it might not be strong enough to be used with pressurized co2. Is there like a cheap or diy manifold of some sort that could be used.
