External Filter Weird Noises

[Natural_Born_Killer]

I run 2 AquaPro 2 external Filters on my 120g.

Yesterday one of them started making a bit of a strange noise but it does that from time to time so I didn't think much of it.

This morning I wake up to it making some very strange noises... really loud.

Any ideas or is it just clogged up or something?

Take them apart. Sounds like it sucked up some sand.

Ok cool thanks...

It was getting so loud that I thought someone upstairs (live in a flat) was doing construction!
