want to replace carbon in my filter

What exactly am i looking for .need to puchase some and dont know what to ask for !!

I have yet to find good carbon to refill my filters. I bought numerous carbon replacement bags I've found and, in the long run, it's better just to buy another filter. They are never as effective.

Foothill filters on ebay, it is the australian mined carbon, far superior to coconut husk and other types of carbon, 2-3 times the surface area. Might check amaozon as well.
Just make sure its the mined carbon and you will be happy for sure.

Peace
