I have the PDZ. I was thinking it would be in larger chunks. It is more of a sand and I do not know how I would put it in a pond filter. Can you really put it is a mesh bag?
For my small ryukins I put it in a throw away food container and set it in the bottom of their tub. I will know by tomorrow if this is effective. No filter.

Takes 3 or 4 rinses to get the dust out.
