From MindStream.. If you were at our workshop at the MACNA conference, you know that it was standing room only. We were thrilled to have the opportunity to present the MindStream monitor and how it will change the way we look at aquarium water chemistry to so many of you. The feedback has been incredible. We have also had a few requests to share the presentation for those who were unable to attend, so here is a link to the workshop presentation created by one of our founders and analytical chemist, Giuseppe Petrucci, for the event. We hope you enjoy it!
