Hello, I have a 110 gallon tank and have had nothing but good things to say about the Fluval fx5 that has been running the tank for the past few years. Unfortunately, the filter completely stopped working a couple weeks ago and I've been trying a number of different troubleshooting procedures.
When it initially stopped, I removed the filter, cleaned it out, removed the motor and impeller and cleaned the whole assembly. After reinstalling it, the filter ran great for 2-3 days, and then stopped again. I did the same cleaning procedure and reinstalled it, but this time it won't restart. I hear a very very quiet buzz for a few seconds when I first plug it in (with water) and then it will stop and not work at all.
I'm not sure what to do as the tank gets dirty in a matter of days due to the turtle which lives in it, and I have been emptying and refilling the water every 2 days while trying to get the filter to work. I was wondering if theres anything else I can do. The impeller and seals all seem fine to me and there doesn't appear to be much movement/play when reinstalling it.
I'm trying to figure out how to determine whether it's the impeller/shaft, bearing or the motor itself. The replacement motor is over a hundred dollars and the impeller is around half the cost but still very expensive; would rather figure out the issue for sure before buying parts
