Mag 12 Noise

[lastlight]

Yeah the denser foams are better than floss of a more porous foam like an aquaclear insert style because those would trap a ton of crap in them and you'd likely not be rinsing the thing.

I use a mag 12 right now as my skimmer feed pump. it's been running for months and is a quiet hum but it has always sounded like there are little bubbles or grains of material bouncing around inside it. Maybe there are lol. It's certainly nothing you can hear 5 feet away tho.
