I have this skimmer that came with my Aquatop 24g. https://www.aquatop.com/2nd-generation-replacement-protein-skimmer-for-the-rc24eco-rc40eco.html
I have tried every position in the tank and raising it up and down. It produces excessive microbubbles. Been like this for week now. It's not new, but I did clean it about a week ago and that's when the microbubbles came back. Before that is was running fine, skimming, and no bubbles. It does not have any valves and no manual. I tried hanging it off the glass divider they suggest on the site. I know its not the best but since it was working before I'd like to get it working again without having to buy a new one.
