Sorry to tag onto an old thread, but I have had my reactor (same one as at the start of this post) up and running for a few weeks and it seems to be working well. Not too noisy and I seem to get good dissolution of gas. I had quite a few issues priming the system with it attached though, and basically did it accidentally when I removed a pipe connection and it flooded the system (and partially the cabinet). Obviously, I don't want to do this every few weeks, so I have been trying to find something - a 'purge/bleed' valve - that I could attach to allow me to release the air in a more controlled manner. Is there such a thing readily available on the market? What do others do? I note @Zeus. loosens the pipes - this would make me nervous of catastrophe!Just a way of venting air (and CO2) after maintenance/fitting, just makes life easier. I just release the air by loosening the pipe fittings to my APS EF2 after maintenance.
I haven't clean my reactors in years, as when I did do them they was basically clean.
