HELP Jebo skimmer microbubbles solution

[ItsMoney]

i just bought a jebo 180 HOB skimmer and as soon as i plugged it in, microbubbles all over the tank!! ive tried adjusting the valve. i understand theres a break in period for every skimmer but is this normal? does anyone know any mods to eliminate the bubbles? thanks in advance

I have that skimmer and the bubbles will go away with time + proper valve adjustment.
