So when I set up my most recent tank, I decided to change out the filter for the Fluval U4 filter. I put it in there and everything. But when I turned it on all this weird white stuff started coming out of it. Does anybody have any idea what that is and why?

If you didn't rinse the filter media, it's probably dust from the BioMax.

I do recall rinsing it, though lol Maybe I just didn't rinse it good enough. Biomax are the little white things right?

Yep - they're the white ceramic bits. Sometimes it takes a vigorous rinse.

There's no real need to worry about anything in your tank, though, it's harmless dust.

Ahh! Okay thanks
