I have seen threads on micro bubles before but not really clear on if it is bad for the display tank and if it is why is it bad. I have a 55 gallon tank and get some micro bubles in the main display that comes from my aqua clear 50 power head. I have the power head 3 inches from the surface now and it occasionally still spits out a spray of really small bubles. Is this bad? Should I change to a water fan? I also adjusted the flow on the power head to see if that would help. Any feedback would be appreciated.
