TW 1800 Thalassiosira weissflogii
Thalassiosira weissflogii is a large diatom (6-20µm x 8-15µm) that is used in the shrimp and shellfish larviculture industry. This algae is considered by several hatcheries to be the single best algae for larval shrimp. The large cell size (16 X the biomass of Chaetoceros and 3 X the biomass of...

Thank you. but I cannot use this: Instant Algae® products are non-viable algae, meaning that they cannot be used to start cultures.Reed Mariculture carries them:

Good catch there - my bad. Here are some places that sell culturable ones (they're pretty pricy, but they're the only places I know that carry live ones right now):

I've gotten thalassiosira and chaetogracilis diatoms from carolina.com
Price is decent, but they are sold in small test tubes with only about 50ml. I recommend starting 250ml at most and gradually increase volume as it colors up. I use glass erlenmeyer flasks and very low aeration.
Make sure you add silica. I use f/2 and a silica additive from florida aqua farms, but I've used super cheap "water glass" successfully in the past.
*edit*: thal is not tolerant of high par, especially at start so use low light
Thalassiosira, Living
Genus and Species: Thalassiosira sp. Optimal Medium: Alga-Gro® Seawater Optimal Temperature: 22° C Optimal Light: High (200 to 400 foot-candles) Motility: None Classification: Diatoms
