how to fix noisy impeller

I've seen people share a link a couple of times on how to fix a noisy impeller, but am having a hard time finding it now (now that I actually need it!).

If anyone could scare it up, I'd certainly appreciate it.

You can buy replacement impellers pretty readily. Most common cause of noisy impellers is sand getting into the filter. The particles will score the magnetic part of the impeller and cause it to vibrate. You can remove the impeller you have and take a look to see if there are horizontal grooves around the cylinder. Or if you're lucky,enough to catch it early, remove the impeller and rinse out the motor area of the filter to remove any substrate/sand that's stuck inside.

It's a brand new filter (hagen mini, $10). It's very loud and I remember people sharing a link to a page that showed how to fix a noisy impeller using teflon tape.

I think Vaseline or PTFE grease (Teflon grease) are one of the more common methods used. Both are safe for food contact though not designed to be consumed, so I would think they would be safe enough for fish.

I've never had this issue, but if I ever do, I'll be going the Vaseline route

This is temporary though and I would make sure to get a spare impeller -magnet.
