What is your favorite filter media?

I'm a big fan of the Polyfil as well. I've switched to using it in every single filter.
 
Polishing pads by Hagen. They cleared my water in hours ;)
 
another one for pot scrubbers and also ceramic rings, normally pot scrubbers as prefilter then the ceramic rings if they are fully submerged, if not fully submerged as in a wet/dry style just use the pot scrubbers. they have more surface area than bio balls.
 
Let's see how long we can make this thread while staying on topic!:dance:
