Carbon

[reeffreak]

"anecdotal evidence" is a contradiction in terms but then I would agree that old carbon can start leaching stuff back into the tank. Carbon works because it is highly porous and it traps very small particles in its matrix --it makes sense that if it starts to break down it will leach crud back into the tank.

Science often is.

Dennis, I use the same reactor and run both the GFO and the ROX carbon simultaneously 24/7. I change them both about once per month and have not noticed any issues with any of my corals.
