Carbon vs. Ammonia/Nitrite/Nitrate (1 Viewer)

Doing some filtration experimentation & wanted to know what you guys thought.

Can carbon alone handle all the harmful nutrients that plague our tanks?

No. Carbon is for removing organic molecules. It will do virtually nothing for anything in the nitrogen cycle

Can you give an example of organic molecules?

Carbon can only pick up larger molecules, like things that you can see visibly i.e. Cloudiness or yellowing. Ammonia/Nitrite/Nitrogen molecules are much too small for the carbon to filter out. Carbon is ran on lots of tanks on a regular basis and nitrate is still a battle. I run carbon on and off and have never see a spike in nitrate when it's off line.

This is a good video on carbon
