Oh. Stinky. Ya, a few days with no moving water isn't too good for near anything.

Hopefully it won't barf on ya again.

yeah i hope not plus now me and my dad know what to do

I have found that it is good every once in a while to take your filters, powerheads, what ever you have, and take them apart like that and clean them up some. Especially the impeller (the magnet piece with the blades that move the water), pull that out of the socket that it sits in, clean the goop off of it, then use a small round brush to get down inside the socket, there is always gunk inside there.

yeah that's what i think went wrong and will start bi-monthly checks
