I was talking air stones, unless I mentioned power heads in my post? Either way, I agree that both aquariums with or without can be great, but disagree that it only adds some bubbles. The aeration of your water becomes better with adding some air stones, not stating that you need one and never stated that, simply stating that it does add some aeration to your water which compliments the continuous cycle of your nitrifying bacteria and eventually keeps the levels in your aquarium somewhat more stable. Conclusion: air stones are not a requirement, but definitely compliment your tank in both water quality and visuals.
Your quoting me why? I was quoting convict who is correct.
