Air Stone Bubbles

[lexusalan1]

hi all, ive just had a bit of a change around in the tank and moved my air stone, i have moved this to 1 end of my tank so that i could get an effect of the bubble covering one side of the glass. due to the location of the stone the bubbles are getting sucked up in the filter and so the filter is now throwing out tiny bubbles.
although i think that this looks great will it be doing my filter any harm or is there such a thing as over aerating the tank? when i put the stone on it doesnt seem to bother the fish but im more worried about doing harm to the filter bacteria.

i dont see why tiny bubbles would have much of an effect ... filters break when they run out of water
