Hi All
I live in the UK, and all the filters I've ever seen never say anything about a bio-wheel. I've only ever heard you guys mention them about the Penguin and Emperor filters. What is a bio-whell and is this something uniquie to those particular brands, and if so where the do I get an emperor filter from here in the UK ?
