Urgent: A stupid question on external filter

[Justikanz]

Hi! In an attempt to add a CO2 diffuser reactor (Taiwanese brand 'UP'), I accidentally broke the external filter (Ehiem 2xxx series) inlet flow. I tot it was ok and I continue to hook up the reactor. After the reactor's connected, I realised that there was no flow at all from the external filter!... There is no noise from the filter and there is only a very very small vibration (almost dun have) coming from the priming area. Opened up the filter and found that the impeller is not broken...

What is wrong??? I am scared the fish will be affected by the lack of water flow as the tank is heavily populated...

Help?...

*Duh*... As mysteriously as it occured, the problem is solved... As I was sitting there wondering what was wrong with it after I've tried all methods suggested, the filter suddenly made some noise and the flow is back!... I was like *duh*...

Ok, anyone had any idea what was this about?...

Thanks, Vinz, Stormhawk and Wackytpt for the help rendered...
