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.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.
It's used. I thought that was only for new ones?Give it a chance to break in, like a week. It will stop.
I did clean it with vinegar before putting it in my tank.this skimmer needs to be in 7'' - 7''.5 of water. have you checked the venturi .Part that connects to pump .make sure all is clean of salt build up. soak in vinegar ..
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?I don’t personally know that particular skimmer. However there are a few skimmer “rules”
