i recently bought a new fluval fx5.. everything is good besides it overflows. when the canister initially start up it runs. then when it shuts down to get the air out of the canister ... im guessing there is no syphon break... and the water continues to fill in the cansters and then starts to over flow from where the lid connects to the lower part (bucket).. the bolt/nuts are tight.. does anyone have an idea of what the problem is? i watched the video 50 times and followed all the guide lines.. this filter is ruining my basement and my tank is now lacking a filter. i also tried calling the hotline but everytime i was put on hold i was disconnected. helppppp pleeaaasse
