Silica Media Booster

Metasilicate is required for many diatom strains and is important for the formation of frustules. Diatoms need about the same ratio of nitrogen and silicon for growth, with evidence showing a lower growth rate of diatoms in media containing ratios with less silicon versus nitrogen.

Add 1 mL/L of this solution to your media to provide a boost of silica (Final Concentration: 200 µM). The Sodium Metasilicate Add-In Solution is sterile and should be handled aseptically to prevent contamination.
