yeah very happy, the only down side is the amount of mist reaching the tank. but I have got a very yellow DC so might back it off a bit once I've got over my pearling obsession.
on the plus side the mist gives you a good idea on the flow patterns. it's a very fine mist the bubbles are so small they don't reach the surface. I have a much lower bubble rate as a result. I do have the working pressure set quite high to get the bubbles to come through, about 1.6 bar. I had a trouble getting a stable rate to start with but I reconnected all the lines to the solenoid, bubble counter and the atomiser and it has been fine for a couple of weeks.
don't look at the dirty pipes... i'll do them next water change (honestly)
