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.
