| There are two benefits 1. Looks good. 2. Surface agitation from the bubbles allows more oxygen and CO2 to be exchanged.

3. some fish play in them, and get a real kick out of it.
4. some fish (my goldies, on occasion) will use them as an impulse to release eggs. Very useful when a fish is by itself or without a male to stimulate. Also useful if the fish is having trouble and in danger of becoming egg-bound. - not the most important use, by any means, but the one I appreciate most, as one of my fish is difficult when it comes to dropping eggs.

| It should be noted, however, that bubbles can cause problems, especially with larger fish, in that small bubbles my cling to fish's skin and will have an effect similar to a burn. This is rare, of course, but it is not a good idea to add an excessive amount of bubblers to an aquarium because of this. Generally, no more than one column per ten gallons unless running a UGF. MOA

Ok why & what is the difference from running an UGF and not running one when it comes to bubbles?,just currious as I use UGF in my tanks.What is better,large bubbles or small bubbles? I did read somewhere tha too fine a bubble can affect your fish,sort of like the bends to divers.

| Hmm, Could you clarify the question a bit? I'm not quite sure what you mean. As to which size of bubbles are best, that depends on what you're going for. You see, the bigger the bubble, the smaller the relative surface area. This results in a higher terminal velocity. In other words, big bubbles move the water faster. However, because of the smaller proportional surface area, big bubbles don't oxygenate very well and usually don't move a lot of water volume around. On the other hand, very small bubbles have a very high proportion of surface area to volume and thus tend to move greater volumes and aerate better than large bubbles. The downside, of course, is that they don't move very fast and thus represent a lower flow rate (to a degree). As such, the most useful bubbles for UGF's are between 1/4" and 1/8". Also, I've never heard of a "bends" type of reaction from small bubbles used in an uplift tube of a UGF. However, small bubbles in an exposed column can affect small-medium fish adversely in that each bubble will send out a vibration that the fishes lateral line will pick up. If there are too many bubbles (too fine), the fish's organ will not be able to interpret the different signals and the fish may behave as if it were "dizzy." The behavior is similar to people who have inner ear problems, but it only occurs rarely and with specific sizes of fish (2.5-4.5 inches, generally). With regard to air-powered UGF's, here's a link that might prove useful: http://board.fishchannel.com/Topic152887-5-1.aspx?Highlight=air+pump+terminal+velocity MOA
