What did the docs tell you about your pump?
I was just reading the paper work that comes with equipment,It says that the Koralia are guaranteed for 24 months from the date of purchase.
Reckon something just came loose?

I've notice that if it to close to the surface,it draws air into the chamber causing a clanking noise.You're know if to close to the surface if a small whirlpool occur above the pump....just an idea.

they told me to just send it back and they would give me another. i was shocked. no hassle whatsoever. but tonite it wasn't making the noise anymore. maybe it just had something hung in it.
