Silicate fertilizer 8 ounce

New water glass formula, for diatom phytoplankton strains. This is required to grow; Thalassiosira weisflogii, Chaetoceros calcitrans & Pheaodactylum tricornutum. This is a vital element thats required to be used with F/2.  If you are buying our phytoplankton strains they have been fed and have cell density to support 2 ml of silicate per gallon of phytoplankton culture. If you are using our product on a strain that hasn't been introduced to this level, it's recommended to use half the amount as stated. 1ml per gallon on strains that have not been exposed to high silicate levels. New diatom growth will flourish as more silicate is available for them to consume throughout the 7-10 growing period.  Add 2ml per 1 gallon of phytoplankton culture water. Do not premix with other F/2 before you're ready to use. We recommend having your culture water and phytoplankton start in the vessel before adding silicate.  This must be used with F/2 and does not contain everything needed to grow phyt
