Algae Fertilizer (Culture Media and Salts)
Algae Fertilizer (Culture Media and Salts)
Algae cultures need fertilizer, or nutirnets. To grow algae consider that they are in contact with their environment through their cell membranes. They interact with the physical, chemical, and biological makeup of the water. When we culture algae cells we try and control these factors to target the growth of the cells that we desire (think about how a farmer would want sandy or clay soils for for different crops). There are general types of water that are used to culture algae
- Freshwater (Chlorella)
- Seawater (Nannochloropsis, Pyrocystis fusiformis, Porphyridium, Isochrysis)
- Alkali (Arthrospira aka spirulina)
Media is made up of both SALTS and NUTRIENTS. Freshwater salt concentrations are very low, we believe in adding a small amount of carbon buffer to the media (pH 7). Seawater is largely sodium chloride (pH 8.2). Alkali salts include both sodium carbonate and sodium bicarbonate (pH 10)
Nutrients like our spirulina and f/2 are a complete mixture of everything that a culture will need. The content of the nutrients can be described in two key groups:
- Macronutrients: nitrogen, phosphorus
- Micronutrients: trace metals, vitamins
All of the Algae Research and Supply salts and nutrients are made in our labs and are as good as it gets for growing algae!
Algae Research Supply: Algae Culture Salts, Spirulina Alkali Media
$ 3.50 $ 15.00
Our spirulina salts are a modification of the media from Aiba, S. & Ogawa, T. (1977) and Schlösser 1994. Using this media you can achieve good rates and maintain pH control. View full product details
Algae Research Supply: Algae Nutrient Media: F/2
$ 4.95 $ 19.99
F/2 is a widely used general enriched medium for growing algae. The original formulation from Guillard and Ryther 1962 has been slightly modified for growing freshwater and seawater strains of algae. This is a complete media. View full product details
Algae Research Supply: Complete Media Kit (salts + nutrients) for Arthrospira platensis
$ 7.99 $ 42.75
Included:
1) 50 ml of concentrated nutrient media
2) Salts, (sodium carbonate, sodium bicarbonate, and trace metal containing sodium chloride)
3) Instructions for cultivation Description:
INCLUDED: Nutrient Fertilizer, Salts, and Instructions. Spirulina is the common name of the colonial blue-green algae Arthrospira platensis. Spirulina is commonly consumed by humans and animals and it's blue pigment phycocyanin has medicinal and biotechnology value. Our culture is grown in our laboratories and it is concentrated prior to shipment.
The nutrients are a modification of the spirulina media developed by (Aiba and Ogawa 1977, Schlösser 1994). It uses NaNO3 (sodium nitrate) and NaPO4 (sodium phosphate) as the nitrogen and phosphorus sources. Our salts are a combination of sodium carbonate, sodium bicarbonate, and sodium chloride. We are supplying all the things that you need to grow algae that you don't already have in your basement, or could buy from your local pet shop.
YOU WILL NEED: A starting culture (also available from Algae Research Supply on Amazon), chlorine free water, a growing vessel (such as a 10-gallon fish tank), air supply (small air pump, not the band, but if you could get the band to sing to the culture- that would be amazing!).

Algae Research Supply: Enriched Seawater (f/2) for Culturing Marine Algae (1-Liter)
$ 19.95
This is a common and widely used general enriched seawater medium designed for growing coastal marine algae. The concentration of the original formulation, termed "f Medium" (Guillard and Ryther 1962), has been reduced by half.
This media is disinfected using UV radiation.
The default is WITHOUT silica. Please comment if you would like it with silica (for diatoms and other silica requiring organisms).
Great for dinoflagellates, especially bioluminescent Pyrocystis fusiformis!

Algae Research Supply: Nutrient Media, Spirulina
$ 6.95 $ 19.99
Our spirulina media is a modification of the media from Aiba, S. & Ogawa, T. (1977) and Schlösser 1994. Using this media you will have good rates of growth and be able to have maintain replete nitrogen concentrations and thus a high protein product. View full product details
Algae Research Supply: Secchi Stick
$ 2.00
The Secchi Stick is a simple analytical device to determine optical density of a liquid. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity. We have a video on it's operation on youtube. View full product details
