I have a freshwater tank that is themed after the amazon river basin. I did the reserch and got my stocking of fish from that area. Anyway I use blackwater extract in order to replicate water conditions in this area. I never use carbon in my freshwater tanks because I find it useless. It will absorb all the blackwater extract and my water is crystal clear. All my test are good. Can't remember the last time a fish died in my fw tank. I am sure that will change in sw tank lol. So should I use carbon on sw tank? & why?
