Been out of the game for quite some time and just curious what are the go to options for dual stage reactor? I know it uses to be gfo and carbon but I never liked that option as they need different flow requirements. Are biopellets still a thing?
Basically what would be your go to media to go along with carbon? I will definitely be doing carbon by the way
