Cleaning a Remora Pro.
This is probably a dumb question. But those of you that have a remora, or remora pro, how do you go about cleaning the collection cup? What I mean is do you unplug the skimmer before you remove the cup, or just leave it running. I have been turning it off and restarting it, but it seems like when i restart it, it gets very noisy for a while and a million microbubbles go into the tank. I read the instructions that came with the remora but it doesn't mention turning it off or not.
Thanks for any help.
