I have 3 fish currently in my tank with a over sized skimmer and I am no longer getting Microbubbles. I took everything apart and took apart the pump and cleaned it out and finally I no longer have Microbubbles leaking into the tank

I think cleaning the pump solved the problem. Yes the skimmer is foaming but obviously not a big amount due to the low bioload but it is working
Good to hear you got it resolved through cleaning. That said, a lack of dissolved organics can in fact result in microbubbles. This is particularly common when a skimmer is setup in a brand new tank where there is a lack of dissolved organics and something I've experienced in my own new tanks with a wide range of skimmers as well as some tanks that I've installed for others over the years. Either way, I am glad it is working better for you now.

Have had my BK mini160 with the RD6 pump for about 3 weeks now. Its not performing as I'd hoped it would in my scenario. I have a few questions please.
I've tried anywhere between 7.5 and 8.5 inches of sump depth as well as running the pump from 50% to 75%. The issue is with foam production or the lack thereof. The tank is mature at 2+ years and my prior skimmer pulled plenty of skimmate prior to it being replaced.
I'm sure its a simple adjustment but cant seem to get it right.
The directions say there should be a maximum water level mark on the skimmer body but that doesn't appear to be on mine. I also have an extension on my bubble plate of acrylic that extends up from the plate in a cylinder shape that's about 2-3 inches that doesn't appear anywhere in the images or manual.
I currently have the water level 3/4 of an inch below the collection cup. I do have skimmate but its collecting on the skimmer body and not extending up into the collection cup. I've tried removing the resonator and running just the bare intake in hopes of getting more air but that didnt seem to make much difference.
Any suggestions?
Thanks!

The bubble plate extension is the new design.
The high water mark is no longer included on the skimmer bodies. Ideally you’d want the line where bubbles turn to foam to be about an inch below where the cup sits on the body but depending on the load you might need to go higher than that. You just don’t want to go up beyond the bottom of the collection cup unless you don’t mind water seeping out between the cup and body. Particularly if the load is light relative to the skimmer size. How many fish are in the display? As I recall it was around 10 fish? I think the issue is the light load so I’d raise the level up inside the skimmer by closing the wedge pipe a bit more. Get it to the bottom of the cup. That should improve the skimmate production. I would do that with the pump set to about 50% and see how dense the foam looks.

10 fish averaging 2"...Water volume is about 140 gallons give or take.
I can try raising the water level until I see foam collecting in the cup.
Can you explain how the speed of the pump affects foam production?

The air draw and water flow is tied directly to the pump speed. The higher the speed, the greater the flow into the skimmer. You want to use the pump speed to get the most dense foam head possible and use the sump depth of wedge pipe to adjust the level inside the skimmer. The lighter the load, the higher the line where bubbles turn to foam (break line) will need to be inside the skimmer. As you increase the speed, the contact time is reduced and there is a point of diminishing returns in terms of speed as you end up creating turbulence in the skimmer and too many bubbles which can make the foam head unstable due to lots of bubbles bursting at the surface instead of creating nice dense foam. Since very tank is different in terms of load, there is no right speed for the pump. It really boils down to fine tuning the pump speed for your load and finding a setting that results in the thickest foam.

Also keep in mind that you need dissolved organics to create good consistent foam. Your load is VERY low and the fish you have aren’t creating that much in the way of dissolved organics even for the 160 sized skimmer. This is one the reason why you will need to raise the level inside the skimmer as you are running it to dry for your load (or lack of). By doing that, you are effectively reducing the total volume needed to fill the neck with foam in order to see skimmate in the cup vs collecting on the sides of the neck and upper body.

Very Helpful, Thank you!

I'll try making small adjustments over time and see whats what.

Thanks again for the clear explanations.
