Plankton Culturing Log

I have decided a while ago to try my hand at culturing phyto- and zooplankton. It started out as something I thought would be easy and cheap, but I was quite wrong. That being said, I am sure you can make it work for less, but that is not my way.

I will fill out the details of this endeavour as I progress. Below is an event log.

Harvested 1.5L of both Nannochloropsis cultures, replaced with sterile saltwater. Algae count were above 8 million cells per milliliter. Harvested 70% of the rotifer culture as the density seemed high by visual inspection, and observation under the microscope showed that most rotifers had either no eggs or as single egg - as far as I understand that implies the culture has reached a plateau.

500mL of Nannochloropsis was fed to the tank, and the concentrated rotifers were fed to the tank too.

Not sure but it looks like I lost my Rotifer culture. I do not see any rotifers anymore.
