Scaling UP! H2O

207 The One Where We Revisit One Of Our Most Popular Episodes

Welcome to the water treater’s favorite podcast, Scaling Up! H2O. I’m your host, Trace Blackmore and for my long-time listeners, today’s show is going to be a little bit different because for the first time ever,  I’m re-releasing one of our most listened to episodes for our newer listeners. 

I recorded this show on October 27th, 2017 and upon listening to it again, I can see why it is one of our most shared and most downloaded episodes. There are so many good questions that the Scaling Up Nation submitted, and I’m grateful for the opportunity to answer them.

My hope, when I first created this podcast, was to inspire a love of learning for any of its listeners. So please join me as I answer your questions, and if you have a new question for me, please reach out, I’d love to do some research and answer your questions on a future episode!

Thank you for listening!
