Also be prepared for cyano issues at the start. Some people get away with it, but you'll find literally hundreds of threads on the web in which people got cyano explosions shortly after starting the pellets. It looks like cyanobacteria can also metabolize the carbon polymer that gets sloughed off the pelllets as they tumble and makes it in to the water column, so if you're going to run pellets it's strongly recommended to routinely dose a probiotic supplement to help out compete the cyano.
When I added pellets to my old 90 gallon (that had been running for a year), my whole tank was a thick carpet of cyano the next week. This time I added them right at the beginning and haven't had too many issues.
