I recently bought an emporer 400. I was looking through the library and ran accross this http://www.cichlid-forum.com/articles/power_filter_tricks_v.php. I don't know if I bought the right stuff to put in the cartridges. The only stuff I could find at the local Petsmart is Marineland's Premium Carbon- Ammonia Neutralizing Blend. It is little rocks but I don't know if it will work. What do you think?

It should work as a biomedia if it does not break down into smaller pieces and work its way out of the matrix. The reservation I have about this conversion is that with more parts, comes more opportunity for something to go wrong. There was a Danner filter called the Skilter that doubled as a skimmer. It did a good enough job if set up just right, but with all the parts, it was not something everyone could assemble correctly.
