Im setting up my 50 gal and my (slightly used) filter pump is leaking (pretty sure the rubber seal is just worn). Can you buy replacement seals? The pump is a Millenium 3000. any help is appreciated. I really don't want to have to buy a new pump...

haha nevermind about the leak. fixed is with sealant ribbon. but the pump is now making a sound like there is air trapped in.... kinda loud...
