Grotech outs its new CoCo carbon, although this name sounds like a delicious hot chocolate drink of some kind Coco actually stands for something else. Coconut. Grotech is bragging that Coco carbon will outperform traditional activiated carbon by as much as 50%. Needless to say we will have to wait before this is imported into the US as a 1000ml plastic jar of the stuff will set you back EUR 14.95 ($19.32). Our biggest question is if it smells like coconut as our sumps could use all the help they can get in the “smell” department.

I would be concerned with the acidifying properties of coconut, not sure how grotech treats this products to prevent is from lowering pH, even more than standard carbon.
In the past, all of the coconut carbons available to the hobby were vapor phase carbons and did a poor job for our application or were only good to remove Chlorine in an RO/DI system. What changes have they made to improve this?
