totaly bogus.. like Brad said the more bubbles the more surface area. this is why the beckets were made.. to increas O2 levels in ponds to promote healthy ponds.

This has the potential of becoming a good discussion if the flames can be kept out of it.
I am going to stand behind my original statement because it has the accumulated weight of scientific evidence behind it.
When you speak of more surface area you seem to be looking at the reverse of what is proven to be true. In a bubble rising to the surface you have a gas to water area. That is opposite to the surface where you have a water to gas layer. Thus no meaningful gas exchange can occur.
I will give you one thing though. The bubbles bursting on the surface will increase agitation thus more oxygen will be taken up in that area.
Anyway without appearing to be a flame, that is the way I understand it to be from extensive readings. OKAY????
