So what's the difference between that and my 900gallon air pump? I watched the video...http://keepalive.net/movies/KA1100.ram (real media)...it looks like the bubbles are finer but not really about to drop $60 for one.

Take a look at at the air bubbles produced by an aquarium aerator. Watch how quickly the bubbles rise to the surface. They provide little aeration, but are aesthetically pleasing to watch. Bubbles must remain contacting the water, if they are to do the job properly. A good rule of thumb is: The smaller the bubble, the longer it will remain suspended in water to dissolve.

The smaller the air bubble, the more slowly it will rise, giving it more time to dissolve in the water.
Due to the higher density of salt water, air bubbles are usually smaller in salt water than in fresh water.
A large 20mm bubble has a volume of 4.19 cm3, and a surface area of 12.6 cm2.
You could make 260 small 3mm bubbles from the large bubble. They would
have a total surface area of 83.6 cm2. This is 6.6 times the surface of the 20mm bubble.
The small bubbles, can theoretically aerate 6.6 times as much water with the same amount of air.
Knowing the importance of air bubble size, the effectiveness of different aerator systems becomes readily apparent! ​

Ah, so like a diffuser on a bong. HA. Great info.

I'll let you know bro will be firing up my DWC setup in the next few weeks with a batch of clones. I ordered the Fish alive oxygen diffuser today.

one thing i should mention to you all, the oxygenator you all see in avatar has an airline attached to it & it's also in salt water, in salt water you can see the tiny bubbles a lot clearer than you would in fresh water, in fresh water to see exactly what you are getting, place the back of your hand in front of the oxygenator & you will see the same bubbles, thought i would clarify that a lil before you all go and order them & don't see the same as in my avatar

manufacturers quote....
These videos are taken in fresh water so the effects of pure oxygen can be seen. The properties between fresh water and salt water are different, and so the visual effects are different. Fresh water bubbles are nearly invisible. However, the results are the same.
