Bubbles in tank with protein skimmer not running

[Fishbro]

In my Biocube 32 I’m getting tons of bubbles in the tank without even running a protein skimmer. What could be the cause of all these VERY unattractive bubbles? It really takes away the appeal from the tank but I’ve noticed that the bubbles seem to be shooting out of the return nozzle if that helps at all.

Air is getting into the system. Your water low?

Low water or air in the pump.

In my all in one tanks I notice bubbles when the last chambers water level is low causing splashing

Ok so I just checked and my water in the back chamber was a tiny bit low so I topped it off it did actually look like it was creating some bubbles. I’m going to check the return pump also to see if there’s any gaps or something that’s making bubbles.

Didn’t seem to do much I think the return pump is pretty old could that be the cause?

Low water or any waterfall affect in the last chamber will create micro bubbles so I would start there.
