I got my 2 stage on ebay from affinityaquatics in OR.Thanks for sharing, any recommendation on the brand for the 2 state regulator?
Also, where do you even go to get a CO2 tank to begin with, and where do you go for refills?
I get my co2 from a welding shop.
My Tunze 3171 is small and efficient.
It is sitting in my 40 breeder sump.
It drips into coral bones but is really not needed if tuned correctly.
