Chlorella vulgaris Cell count and Secchi Disk Depth vs Dry Weight

Chlorella is a microalgae when it is separated from the water and dried it has mass that we call the DRY WEIGHT.  We express that mass in ratio to how much volume of water it was growing in (mass per volume). 
Using our Secchi Stick, you can estimate how much Chlorella you have grown.
