What is the difference between aquarium and brewing co2 regulators?
So I'm currently setting up a low tech planted tank and am looking to eventually upgrade to something more high tech as I become more familiar with everything. So in the meantime I've been looking into setups and price, and came across a whole bunch of different kinds of regulators for home brewing/growing etc and was wondering what the main difference was between these and the more expensive aquarium kinds? Is there something one should be looking for specifically that is better for aquariums? Thanks!
