True but it also happens in other places.

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. what you are probably thinking of is thoes bubble walls .. compared to Vigerous surface agatation the only help a little.. compared to nighting.. they help a lot. with the small surface area of a becket you actualy have a very efficient method of adding O2 to a tank.. my tank has barly any surface agatation now and I have lots of O2.

Providing it is well ararated no it shoulden't.. BUT in a new 20 gal tank with agressively growing algae and such the )2 level can be depleted at NIGHT time.. this is why you have to make sure your surrface agatation is high at night also (or run a skimmer).
