You can order from florida farm directly. I've done that before and its ok. Or you can make a trip to singapore, any one of us will be happy to bring you to those shops selling phyto culture stuffs. :lol:

Reborn sells the ferts... but the culture likewise looked a little... erm... unhealthy...

Anyone know's the chemical composition of the ferts? Can probably mix up a similar batch...

Better dun go DIY your own fert. Would have undesirable consequences if you start dosing the phytos into your main tank.

There are 26 recipes for culture mediums - but the most common used are the L1,K and f/2 formulas.

Guillard's f/2 formula (florida farms)

version-Guillard & Ryther 1962, Guillard 1975

To 950 mL filtered seawater add:

Quantity - Compound - Stock Solution - Molar Concentration in Final Medium

1 mL - NaNO3 - 75 g/L dH2O - 8.83 x 10-4 M

1 mL -NaH2PO4 · H2O - 5 g/L dH2O - 3.63 x 10-5 M

1 mL * -Na2SiO3 · 9H2O* - 30 g/L dH2O* - 1.07 x 10-4 M*

1 mL - f/2 trace metal solution

0.5 mL - f/2 vitamin solution

If u are looking for a pure strain - the best & robust one will be Nannochlorpsis Oculata - cell size 2 microns.

*Nannochlorpsis a unicellular microalgae, member of the Chromophyta phylum, class Eustigmatophyceae, with an average size of between 2-4 µm.

May not a good idea to use seawater as phyto source. Seawater might contain other nasty stuffs such as bacteria,etc. Also can't use the normal plant fertiliser. You might indirectly add more phospate in your aquarium.
