I'm planning (hoping!) to finish getting my new tank set up tomorrow and the tenants moved in. I had been intending to use my backup submersible filter in this tank since a) it will be hidden behind lots of plants, and b) I have it on hand. I pulled it out tonight to get it running in my current tank so it's ready to pop straight into the new tank. I filled it with media I keep floating in my canister filter then fired it up. Boy is it NOISY!!! I remember it having a bit of a rattle when I last used it, maybe I've just been spoiled with a canister, but it seems really loud now. Does anyone have any tips on how to hush these things up? Perhaps it's due for a new impeller, or should I have lubricated edit before firing it up again? Ultimately, since this will be the goldfish tank, I'd like to get another canister, but I wouldn't be able to the LFS which sells them cheaply for another week or so, so what's my best stop-gap solutions? Thanks!
