Skimmer help

I've never had a skimmer before. I've been watching videos but I can't find an answer to this. Bubbles come out from the bottom part where the pump goes in. How do I fix it?
 
I don’t personally know that particular skimmer. However there are a few skimmer “rules”
First off are you certain you have it at the correct water level. Skimmers generally have to sit in the water at a certain height. (This is not the case with a dual pump skimmer) As an example my reef octopus sits in 9 inches of water. And does not like that water height to change.
secondly. You need to adjust the flow going thru the skimmer and this is were I believe your issue is. I can see in the video that bubbles are foaming right out the top of the skimmer you need to dial the skimmer back. I believe your bubble issue down low is simply backup from the incredible.... actually excessive amount of foam being generated. For more detailed help please post the brand type and size of skimmer and system volume.

I believe he is talking about the air unattached to the pump.
I would check the airline is not cracked and no holes as that will release air.
The hose must fit snug in the pump, cannot be loose or stretched out.

To me, it looks like the bubbles are coming from where the pump goes into the skimmer part at the bottom. It's a SCA-301. In a 40B with a 20 sump. About 50-55g total water volume.

Check the venturi on the skimmer and make sure that it's all the way in place. It's possible that it may be loose and forcing air bubble out through the gap. Also whilst you are at it, make sure the venturi isn't cracked. The picture is just for reference

So I took a second look and i noticed the air isn't coming from where I originally thought. It's coming through the pipe that you use to make adjustments at the bottom. Any ideas?

If the micro bubbles are going into the return section, try experimenting with placing a piece of aquarium foam at the bottom of the blue pipe
