Water quality parameters log (weekly):
Salinity by specific gravity, adjusted to range 1.034 to 1.039
Temperature chilled to range 56 F to 57 F. This has caused the room to be significantly warmer for humans, but that’s okay.
By the way, found some content about abalone decline in California: https://www.kqed.org/news/11981665/climate-change-induced-heatwaves-are-devastating-californias-kelp-and-abalone
what methods have been attempted in the past for raising green abalone?
at what depth do green abalone thrive in the ocean?
do green abalone live in a place where water is in constant motion, in a tidal pattern or in some kind of surge pattern or in some kind of pattern of waves?
does an aquarium habitat need to replicate whatever water motion pattern would be natural for the green abalone?
we will begin the nitrogen cycle using ammonium chloride. We had bacteria to convert the ammonium into nitrite, and others to convert the nitrite into nitrate. What are the oxidation states of the nitrogen in each of these compounds?
what is the biochemical reason for the green abalone sensitivity to the nitrogen cycle?
what are the chemical reactions that bacteria perform as part of the nitrogen cycle? What are the reactants and what are the products?
what are the names of the enzymes that the bacteria use for nitrogen cycle conversion processes?
what is the biochemical purpose for the nitrogen cycle conversion reactionsdone by bacteria in the ocean?
what are the mechanisms of action for the enzymes in the nitrogen cycle?
what is the correct pH for the green abalone habitat? Does the pH change seasonally? Why?
does water hardness matter for the green abalone? What is water hardness?
Temperature changes and what they do
Salinity, chlorine

Nancy Caruso, from the environmental restoration group GetInsipred, Inc., has furnished us with technical advice. She obtains permits for direct restoration of organisms to underwater locations where they have been depleted along the Orange County shoreline. Our project will be one of several assisted by Nancy Caruso.
Our equipment comes from Learning Equipment Supply Service, another 501c3 non-profit organization.
Marvin, Moira, Amber, and Zinedine are interested in helping me with the setup and maintenance of the tanks and nitrogen cycle. My Chemistry 150 class will use the nitrogen cycle here as an application of oxidation/reduction and acid/base calculations in class.
We will grow red abalone first, to verify that our methods result in abalone survival. Then Nancy will supply us with green abalone to grow. After seven years of growth, the abalone will be restored to the ocean with the help of Nancy and some volunteer divers.
