Aqua one skimmer- micro bubbles

[dpracing]

I have just got a new aquarium.
Skimmer is in sump but even still the micro bubbles coming out are making its way to the other chamber of sump. This in turn is pumping all the bubble into the display tank
Skimmer is a aqua one g216

Any advice?
And skimmers out there that don't release micro bubble into tank ?
For a 90 litre tank ( 20l sump)

All new skimmers go through a break in period. Once the skimmer develops a slime coating inside usually the bubble go away. Many people report it takes a few weeks for the skimmer to break in. Patience is probably al you need.

It was producing good bubbles until I played with it.
Now it won't produce any bubbles. Helps of micro bubbles in the body but no bubbles above waterline
