The "bubblers" are air pumps connected to air stones. They provide a benefit in that when they reach the surface, the bubbles aggitate the surface and allow gas diffussion to occur at a faster rate. They do provide an attractive addition to the tank but can certainly benefit where there are more fish than the tanks surface area can support.
(BTW not judging, but could you have any more threads going????)
