Nice to have pictures again!
I just switched the powerhead I was using to one of these contraptions. Didn't change the bubble rate and the next morning had to save the fish from suffocating. Reduced the bubble rate in half and still had to add a powerhead to stir the water surface so the fish stop breathing heavily.
Other than watching out for increased levels of CO2 this is it - the thing works every time.
