I Just stumbled across this very interesting read and couldn't find anything yet on Tonmo to explain easily in detail how the skimmer actually works. I myself am still very newbish when it comes to the technical aspects of how things work. Sometimes I don't remember either. (old age setting in) And sometimes having something explained so simply to easily understand and share with others is great. If there is a post about it, or if I have placed this in the wrong section please feel free to remove or place it where it belongs. What Is A Protein Skimmer And How Does It Work?
