[Digestion] Digester for Algae waste

[Zietsman, Rex]

Hi Mike,

All help will be gratefully received. I have got some university guys
helping (they currently run two raceways that are similar in size to the
units I want to finally install) and hope to go and see a spirulena
raceway down the road some. This gentleman produces a product that is
about 6x the potency of normal spirulena.

As soon as the pond is built, I will send you photos so that you can see
what it looks like.

Thanks for you kind offer.
Rex

I would sure try to help you from my experiences working with algal
ponds, 
and remediation ponds.
