M V Bhaskar,
Do you have a feel for how well the Nualgi mix would recycle in an open-ocean bacterial anaerobic digestion process? With bacterial anaerobic digestion, you should be able to use Nualgi to start a bloom and then keep the bloom going by recycling the nutrients.
Does your success targeting diatoms with Nualgi suggest you could make other nutrient blends that would suit macro-algae or other aquatic plants?

Hi Everyone
I joined this group today and this is my first post.
We are working on a very specific solution of using Diatom Algae to
solve many problems.
I have been reading about the issue of Ocean Fertilization for the
past 1 year and find that there is some ambiguity in the literature.
The intention seems to be to cause bloom of Diatom Algae but the word
phytoplankton is used more often.
While Diatoms are phytoplankton, there are many other phytoplankton
other than diatoms.
The latest iron fertilization experiment - LOHAFEX is considered a
failure because it could not cause a bloom of Diatoms using Iron
Sulphate.
The post below says -
>fertilising the oceans with nutrients in order to produce more phytoplankton to soak up atmospheric carbon dioxide.
We are being more focussed by proposing the use of silica and micro
nutrients all in nano size to cause a bloom of Diatom Algae.
Our product is patented in US, # 7585898, Composition for growth of
Diatom Algae, Mr. Thothathri Sampath Kumar, Bangalore, India.

Nualgi contains Silica and all the micro nutrients required by Diatom
Algae - Iron, Manganese, Zinc, Cobalt, Molybdenum, Sulfur, Calcium,
Boron, Potassium, Magnesium, Chlorine. The powder is stable in water
for a long time and the nano particles mix and spread out into water
very easily.
Thus Nualgi is a very good substitute for simple Hematite ore or Iron
sulphate thats been used in the Ocean Iron Fertilization experiments
till date.
Diatoms not only absorb CO2, they also consume nutrients - Nitrogen
and phosphorus, increase Dissolved Oxygen in water and are the natural
food for fish.
Therefore a controlled and steady bloom of Diatoms can be used to
solve many problems - low DO level in water, low DO level causes fish
kills in small water bodies and dead zones in oceans. In fact low DO
level is caused by other Phytoplankton - Cyanobacteria (Blue Green
Algae) and Dinoflagallates, when they crash. A steady bloom of Diatoms
can prevent the excess bloom of harmful and not so useful algae.
We have been solving blue green algal blooms in fresh water lakes in
India using Diatom Algae.
Dinoflagallates cause Red Tides.
We are confident that Red Tides too can be controlled using Diatoms.
Fish population in the oceans is declining, Diatoms are the natural
food for fish - diatoms are consumed by Zooplankton and these by fish.
I have seen a report that the fish population of the oceans has
reduced from about 7 billion tons 200 years ago to 2 billion tons at
present, but could not confirm the numbers. Diatoms can help restore
the fish population and the carbon in the form of Calcium Carbonate in
the bones of the fish would also help sequester.
I look forward to a debate on the issue of Diatoms vs other
phytoplankton and Nualgi vs other micro nutrients.
