? about air...

[reeferj]

Because of my tank setup, I run a cheapo surface skimmer on my left tank that transfers surface muck from one tank to the other tank which houses my overflow. During this process, once in awhile air is pulled down into the skimmer and results in a cloud of microbubbles in the right tank. what ill effects could result because of this much air being pulled into the water? besides the look of the bubbles, which doesnt really bother me. sps being directly blasted with air....problem? Once the bubbles break the surface it almost mimics the foam from a crashing wave, Im thinkin this is helping with gas exchange? Any thoughts/comments

I have had some corals thats seem irritated with bubbles, but no real damage thats I've ever seen.

I would thing the biggest long term issue is going to be salt creep.

Also I would imagine that that many bubbles may really cut down on the effectiveness of your lighting too.

Should be fine. Like you said natural skimming from the "crashing wave" look.
Only thing it would bother if done long term are the gills of your fish.
