Airlock plug. to let you get all the air out of the filter as well as fill it to the top. well thats what i use it for. lol

Does it come all the way off? My filter has a buzzzing sound like a airlock but i can get rid of it. Doesnt matter what i do.....shake refill...restart...has new O rings in it

It should be locked. As Rockerpeller says it gets the air out plus helps to fill up with water. Whatever you do, don't take it out with the inlet hose still turned on cos water goes EVERYWHERE!! :lol:

don't overturn that tab. if you go too far it won't come out. line the arrow up square with the "open" label, and take your time pulling it off. it'll be pretty hard to do after it has been ran.

what i do is turn off the intake from the tank, turn off the outflow, move the filter to the shower (saves getting my tank stand wet) then open both taps to let the pressure out. then try the tab and it should be easier. :)

once its off do what you have to do with the filter ie clean the foam etc, reassemble, fill with water thru the tab til its full, reattach the hoses/taps, then crank it over. should be good after that.
