I really can't figure out what the hell is going on. I have a jbl reg ect going through a up inline atomiser. I had it turned off for about 2 weeks cyz u had a hair algea outbreak which I was zapping with excell. Before I turned it off I had a lime green dc. Since I've turned it back on the bubble rate has slowed so much it's barely bubbling even tho nothing has been changed, the tank is about 3/4 full, when u turn the needle valve up it makes no difference, the pressures are all fine. Now I stripped it all down and the co2 is blowing thru fine, attach it back up and it slows again. So I cleaned the atomiser and still no diff. Any ideas before the hair algae comes back? Could the atomiser be knackered and it's causing some kinda back pressure?
