Growing Green stuff (Seaweed) when living next to an Ethanol Factory that produces CO2. Here in Australia. Hope for the future.

This is a win win. Our business partner is taking it to the next level. Check this 8 minute video out. The way of the future we hope.
Using the CO2 from the ethanol factory to percolate thru Pia's tanks. Envious!!

Needs CalMag.
