I have recently updated the Foz Down web page with the stores that carry it for sale. Here is the updated page.

For people in the Langley, Abbotsford, Chilliwack, Hope area you can purchase directly. If there is no local store to you I believe Eli(Fiji Reef Rock) ships as well as myself.

I have seen clam filters successfully used. The 150 gallon system had over 50 large clams and a ton of fish with no algae problems.
