You talking about GAC filter? They usually are not any good after 1 or 2 weeks. I have a good link at home I`ll post when I get home.

i dunno what GAC is....its just like a regular ole filter you suction to the back of the tank. idk?

GAC is granular activated carbon. It`s a filter with carbon in it right?
