I've been a little stuck on this subject for awhile now, i have successfully been able to keep 3 diffent sp. of algae alive chlorrella spiralina and nano chloropsis also i can grow the total volume of sulution, as far as increasing density and harvesting it hasn't looked very good. additionally there are subtle details about the modifying the quality of the light or different nutrient introduction methods and ratios...basicly I've gotten to the point were i have a usable bulk culture seed, now i need some hints to actually use them in a meaningful way, so I'm asking does anyone know about this? or know about a book or website that clearly outlines the details?
