I am restarting my 55 gallon tank after a number of years dormant. I have Fluval 303 filter with a damaged impeller. I found one dealer on line selling the part and I'm wondering if its worth it to buy it or should I start over with a new filter? The rest of the filter parts appear to be okay but I won't know for sure until I put all of the hoses together and put it in the tank. I originally got the filter in 1995 and had the tank running for several years then restarted in around 2008 or so until 2012.
