No idea where part come from?

I took my koralia 2 out the tank to give it a scrub with a toothbrush, put it back together but, there is a black washer from somewhere, anybody know where it goes?

 

Could I see a picture?

 

Some where there needs to be a tight seal, look around. Luna

 

Isnt that where the power cord goes? Luna

 

also may i just add the white stick that runs through the spinning thing?, i snapped it of , i know what a dip$%£", anyway it still works but is a bit loud, is there anyway i can fix it like super glue or would this leak into the tank and kill everything, stupid question i guess, what else could be done?

 

no even if it did how could it come off in one the plug and powerhead are sealed...

 

Normally your white thing will be included of you just by a impeller replacement, assuming I have the visual correct.

Also is that actually a washer? Does the center whole go all the way through? If not it may br the bearing that holds that "white thing" in place.

 

the white stick is stuck in and broken off in the powerhead cage, so would have to come with the cover, the hole does go all the way through it sits over the stick inside the powerhead to stop the cogs rubbing together creating noise,

 

The washer goes in the hole that the propeller sits in. Just set on the propeller before you push it back in.
