Hi, Could someone please tell me if getting thousands of tiny air bubbles in my tank from my skimmer is normal.
 
Is your skimmer new? Generally brand new skimmers will dump substantial amounts of bubbles into your tank. Also, if the surface tension changes or decreases (with the addition of oils and hydrophobic compounds from food or your hands), then you'll also get a ton of them. Other additives like stress coat and similar products will make it do that as well.
 
same problem here.

ever since my skimmer got cleaned and working properly, there is tons of bubbles getting into the tank.

got so bad that it killed one of my kenyas trees...
 
Bubbles should not and won't kill a kenya tree coral. I suspect something else as the culprit. It may irritate corals if they aren't used to the bubbles, but I haven't seen them kill an entire colony (I have seen trapped bubbles kill very small amounts of tissue on some SPS corals, though).
 
Is it a hang on tank skimmer?
Can you list what brand / model the skimmer is? There might be a simple solution / slight modification that'll solve the problem.

Air bubbles are generally just unsightly -- it takes quite a bit of them to be harmful.
 
It is just a small frag, the one dead was on the sand bed, and the one still alive, but opens very little. The live one is sitting on a live rock right above the one that had died.

the bubbles + my power head gets the whole tank bubbly.

ive adjusted the settings on it to the lowest it'll go to keep bubbles flowing, and still a good amount gets into the tank.

EDIT: I have a coralife 65g hang-on skimmer

Try this method, it worked for me well. Pardon for my dwg and sloppy handwriting. It should work for most HOB skimmers. As someone said, tend to get micros after the feeding w/ my HOB.

A friend of mine had the same problem with his new skimmer, and is normal for a lot of models to do this in the first few days/week. If you let it do its thing, providing it's not stressing any of the tank's inhabitants, it will generally sort itself out in my experience. If however it gets turned off at some stage it will often need to go through this breaking in period again.
