They work well in a wet/dry application just like bioballs do. They have less surface area so they wont plug up easily, but they make up for that with the large quantitys that you can use. When they are submerged there is less oxygen available, so there is less growth. The ceramic media has a TON of surface area due to the porous surface, so there is more area for it to grow on. if I could fill a wet/dry with ceramic media I would, but it's too expensive lol...
(besides that, it would plug up)
I gotta call you on this one rallysman...sorry.
It's not the surface area that's the reason they don't clog up it's the open architecture.
If you could take a cup of ceramics and turn them into a filamentus string the same diameter as used to construct a scrubbie then you would have more surface area than a cup full of scrubbies, of course we've changed the whole game by improving the ceramics surface area now (ceramics as manufactured are dense with a rough surface, rather than porosity like scrubbies)

. (Ok, it was my idea first)
Submerged, they have the same amount of oxygen available to each one. Due to the higher flow rate available with scrubbies, turnover rate will be higher availing more oxygen / nutrients to the bacteria. Scrubbies work equally well at the higher dwell times necessary for ceramics.
Tip: If you go ceramics and have alot of time on your hands, string them (ring or noodle type) on monofiliment line so when it comes time to clean them they lift out as a bunch for dunking,,,Works with scrubbies too.
Nothing wrong with cereamics, just expensive.
