For culturing marine or freshwater diatoms (algae) for fish fry, zooplankton, corals, filter feeders, mussels, clams, oysters, rotifers, copepods etc, a source of silica is required. Diatoms need silica to build their hard outer wall called a frustule and can’t grow without it.
We have a ready-made easy to use sodium metasilicate solution available in a 50ml, 100ml or custom size bottle. 1ml of silica solution along with F/2 culture nutrients makes 1L of diatom culture media.
The following diatom genera are currently available from Aquatic Live Food: Chaetoceros, Phaeodactylum, Thalassiosira and require added Silica.
Add 1ml of sodium metasilicate solution to 1L of diatom culture media.
50ml & 100ml other sizes available, just email.
