Hi all, this mornning woke to a skimmer not working. it has been running with no issues for 3 months. it is a red sea berlin rated for tanks to 250. it sits on the outside of the sump. the mag drive7 pump was working. the chamber was not producing any air bubbles. so i unpluged it, and pluged it back in and got bubbles but it stoped by a matter of seconds. so i left it unpluged. i cant figure what is wrong there are no leaks anywere so im confused to what is going on. i also clean the skimmer cup 2x week even if there is very little scum. please help. my baby shark needs the best water i can provide.
