A little about us

​Hydrospace LLC is based in beautiful Boulder County, Colorado USA. We craft unique microbial products (PNS ProBio™ and PNS YelloSno™). The purple non-sulfur bacteria used in our products are cultured exclusively on phytochemicals (primarily Tellemagrandin II) extracted from Eurasian watermilfoil (EWM).


We obtain our EWM by harvesting it ourselves under direction of the City of Boulder Department of Open Spaces & Mountain Parks. EWM is an extremely invasive and destructive aquatic plant; therefore, your use of our fine products contributes to the restoration of native aquatic habitat!
