• 2 x 1 Litre (Bottle) - f/2 (f2) 2000x Silicate-free - POST DATE (Gamma Irradiated)

AlgaBoost (2000x) f/2 POST-DATE Silicate-free  is a sterile 1000x concentrate of f/2 medium, excluding silicate, for culture of marine microalgae. 

We incude a Vitamin booster: the 'Best By' date of the medium has passed, with a loss of initial vitamin levels, add the Vitamin booster at 2ml per litre bottle of the f/2 1000x silicate-free POST-DATE.    

Almost half the price: an economical substitute for our AlgaBoost (2000x) f/2 Silicate-free

To Make silicate-free f/2: Pour 100ml from the 1 litre bottle, into a bag containing 200 litres of sterile or cooled, autoclaved seawater. Add 0.2ml of the Vitamin Concentrate, aerate and you've got 200 litres of silicate-free f/2 medium.
Formulation: Our formulation is the same as that used by the CSIRO Microalgae Culture Laboratories (AUSTRALIA) & closely based on the formulation of Guillard & Ryther (1962) and Guillard (1975), except for the exclusion of silicate.

Can I use it with diatoms?: You can use this product for culturing diatoms if first you add appropriate levels of metasilicate to the seawater used to make your media. For this purpose, sodium metasilicate pentahydrate is commonly added to seawater at a level of 12.5 - 22.7 mg / litre, although the amount required may vary according to the species of microalgae and general culture conditions used.

Perfect for carboy-scale & bag-scale microalgae culture.

Used in Commercial Aquaculture Facilities, MicroAlgae Culture Labs, Research Organisations and University Teaching Labs.

Conveniently dispensed from a disposable bottle. Just remove the cap and pour (100ml makes 100 litres f/2 silicate free, in seawater).

Contains nitrate, phosphate, iron, citrate (chelator), trace elements (Co, Cu, MoO4, Zn, Mn) and essential vitamins (Thiamine-HCl, Biotin & B12).
