Microbubbles coming from return pipe sump

[Dashing.dayaa]

hey guys... I've been struggling with micro bubbles coming from the return pump..so do you guys have any idea how to resolve this issue.

Are there bubbles in the sump where the return pump is?
Do you have anti-siphon holes drilled in the PVC where the water enters the display tank? If so, are those submerged or above water?
Finally, are we looking at the display, or a refugium zone?

Its a display tank

I can't zoom in, but it looks like the sump is much too full first of all. If you had a power outage, it would surely overflow. Did you test this by unplugging the return pump and see what happens?

Why is the water level in the display so low?

Did you glue your PVC together?

Shine a flashlight in the return section where the return pump is. Look and see if it is only water (bubble-free or not).

I checked the return pump in sump and i see that the bubbles are going from there and coming out in main tank

Believe I was the one that mentioned about your water level. I don't think filling more water to your main DT was a good idea. Your sump has too much water so either lower the amount of water you are draining if you can or check if you have a return pump strong enough to return more water to the display tank
Like someone mentioned earlier, it will overflow if you lose power

Return pump is good and strong and my sump has only 20% water

 

[Dashing.dayaa]

I filled water in my dt because yesterday someone told me to do that
