For this episode, we met up with Eric Tang at Interzoo in Germany. Eric is the creator of Focustronic, and he is making a huge buzz with his very unconventional, out of the box thinking around LED lights, and alkalinity testing and dosing machines. We go in depth with those machines here. Check out what he has to say.

Enjoy.
