Skimmer micro bubbles

[fido19]

hey guys i have a coralife super skimmer (don't hate me) its a hob(don't have a sump) lately its been producing a lot of micro bubbles
i recently cleaned it with warm water to flush out the salt from the pipes and motor
do you think i broke something
i understand that adding trace elements or any form of water nutrient may cause it to get over excited, but the thing is i have done no such thing
i was thinking of getting a filter sock but they are too big for the return pipe

is there anyone else who has had a problem like this and managed to fix this

i have gone through the forums and havent been able to find any answers or a similar thread

aprreciate any info

thanks
