Well I finally hooked up my 1.5" diamater 24" high version of the Rex Reactor on my 150g tank. At one bubble/sec I see some tiny bubbles leaving the spraybar. Some of them dissolve before hitting the surface, some do not.
Do you guys think it's worth building a larger reactor? I can piece together one that is 2" in diamater, 24" high and see what happens, or I can make the current one longer. Which do you think would work better?
