ASM G3 having problems, help

[plancton]

Yesterday my ASM G3 started kicking lots of water, I´ve had 3 years with it, last year I replaced the impeller. 2 days ago I saw it was pumping lots of water, today it is pumping even more, the interior chamber doesn´t look white because of the microbubbles, it looks as if its pumping lots of water but not so much air, yet I verified the air hose and it I put my finger on the hole it clearly blocks the air, so it is sucking air, but by the look of it it seems the air bubbles are leaving through the adjustable with lots of water preasure instead of staying in the chamber.

What is it? how do I fix it?

Is the venturi completely clear?I have to clean mine out every few months. I just use a drill bit and clear all the salt creap out of the venturi body and it stops pumping so much water.

I would agree that the venturi is a good place to start looking.

I just checke it out, it wasn´t the venturi, the maid added to much water to the tank since yesterday, I told her to stop adding water, seems as if the excess in water which probably affected salinity also affected the calibration on the skimmer, I turned it off for a while and now seems better, it would probably go back to normal when the excess water evaporates.
thanks.
