Thousands of micro bubbles after WC?

[Eleni18]

Hi all. Sometimes, after a water change, my skimmer goes crazy and blows a thousand of micro bubbles in my tank. If I unplug and plug back in, it usually calms dow but not today for example. I have a Deltec MC600 and run carbon, phosphate and a poly filter. what causes this and what can I do? My corals are not happy when this happens....

I don't know exactly why, just that it happens. Skimmer is just doing its job. Do you turn your skimmer off during your water change?

I do yes, for about 1-2 hours

Do you have a bubble trap in your sump? Is the skimmer in the correct chamber?

No sump

No sump

Then having no bubble trap is your problem I'm guessing? Not quite sure.
