I was one of the first in calgary to use with Delphinus/Tony... Removed at some point to issues, not with the pellets, just overall. But can tell you that I am running them again. 
 
I can tell you this, first time use, had no algae, when I removed, had algae build up, and had to clean glass daily. With them back in Algae develoment is almost gone, and I clean the glass every 3-4 days, sometimes longer. 
 
For those that ask, why I discontinued the first time. I had major SPS death with RTN. I removed as I thought just maybe it was the pellets, but eventually figured out it was the Kent Carbon I was using. 
 
So I am using Vertex carbon, biopellets with GFO with success so far. GFO and pellets have been running together for about 4 months now.
