Canister filters and power filters are very good at mechanical filtration for saltwater aquariums, but when it comes to chemical filtration the included carbon chemical filtration media is inadequate. The included carbon will help with the discoloration of the aquarium and some smells, but it won't take care of many things harmful to your fish and corals.

This package, for saltwater aquariums up to 35 gallons, includes both Boyd Enterprises Chemi-Pure Blue 5.5 oz and Seachem PhosNet 50 grams.
