HOB if I have to, someday.
More aggravating is what happened with my new canister filter! Everyone told me this thing would be dead silent, I wouldn't even know it's running. Not so- mine has a persistent gentle hum. Which I easily ignore most of the time, it's really only noticeable in the late evenings when the house is really quiet. But it's my own fault it makes a sound at all, I found out.
I'm tempted to try and bend that clip back into shape, but the metal they're made out of seems flimsy, and I'm worried I will snap it in half.
