I need help with micro bubble problem!

[gqlmao]

Hello, my tank recently got a lot more micro bubbles in the display, I don't know how because my sump has barely any micro bubbles because of filter sock and sponges. Its water movement is quite slow also. However my display is getting mad micro bubbles, I have a sedra 9000? the 900 gph return pump. Is there a possible chance that my plumb has a air leak in it?


Thank you

I just went through the same problem turns out I had a leak in the spaflex from the sump to the pump. If your pump is external turn it off and check for a water leak on the input side.

my pump is internal and my water levels are way above the pump. Theres gotta be a air leak someone I just cant find it, I tried reseaeling all my plumbing with an extra layer of pvc glue but its not working and since my pump ius submersed there shouldnt be any air leaks right?
