I have a 20 gallon with 7, 1 inch kribensis cichlid fry and 1 bristle nose. I have a tetra whisper ex20 and It provides fairly good water flow but only in the centre of the tank. I was thinking of increasing the flow to help oxygenate the water. What's would the best way be. Would a powerhead be good, if so how much are they. What other possibilities are their.
