I've got two questions
first ill let you know about my tank- 29 gallons, just got it, has a power filter and there are two dwarf gouramis and two black skirt tetras. i was wondering if i should leave my bubble on all day or put it on a timer
leave the bubbles on all the time. It circulates the water and increases the gas exchange at the surface. There really aren't any negative effects in my expierence to leaving it on.
