Using Cell-hi nutrients eliminates two major sources of error in growing algae; preparation and contamination.

Cell-hi is a complete formulation in a totally soluble all-in-one powder or as a sterile, concentrated liquid form.

All necessary nutrients, trace elements and vitamins have been stabilised so that when made up it contains everything needed for optimal algal growth. Jjust store in a refrigerator or cool, dark place and use the powder at the rate of 100 g per 1,000 litres of culture or the concentrated liquid at the rate of 1 litre per 1000 litres of culture for bag or cylinder culture. For tank culture you can use far less. 

The soluble powder can be stored in a cool dark place or refrigerator for many months

For advanced and tubular reactors giving much higher algal concentrations just use at 2 to 5 times the quantity without harm.

There are three formulations for the all in one powder, and three for the concentrated liquid

All-in-one powder

Cell-hi F2P based on the Guillard F/2 medium and has exactly the same N, P trace element and vitamin content. Most people in aquaculture use this -  1 kg makes 10,000 litres culture medium at F/2 strength

Cell-hi WP based on the Walnes medium and has exactly the same N, P trace element and vitamin content. Walnes is recommended by the UK Culture Collection for algae and protozoa. It is particularly good for flagellate algae such as isochrysis and tetraselmis - 1.5 kg makes 10,000 litres culture medium at Walnes strength

Cell-hi TEViT has all the trace elements and vitamins required by aquaculture species but without the nitrates and phosphates which can be bought locally from cheap fertilizer. Fantastic economy - 63 g makes 10,000 litres culture medium.

For diatoms just add 30 grams of sodium metasilicate for each 1000 litres of culture water after adding the Cell-hi.  

Concentrated Liquid

1 litre makes 1000 litres culture medium

Cell-hi W based on the Walnes medium and has exactly the same N, P trace element and vitamin content. It is particularly good for flagellate algae such as isochrysis and tetraselmis  

Cell-hi NC specially formulated by ourselves for nannochloropsis and chlorella

For diatoms just add 30 grams of sodium metasilicate for each 1000 litres of culture water after adding the Cell-hi.
