✅ Live Arrival Guaranteed — This product is covered by the Texas Coral Ranch Standard. See shipping policy

Chaetoceros calcitrans live phytoplankton provides a silica-based diatom feed that supports copepod production, rotifer cultures, and advanced reef feeding systems.

Widely used in aquaculture, this diatom is valued for its EPA-rich profile and unique cell structure, which promotes strong zooplankton growth and reproduction. In reef environments, it is best used to enhance live food cultures and increase the nutritional value of pods and other microfauna. Due to its silica requirements, Chaetoceros is most effective in systems where diatom growth is intentionally supported. Each culture is grown fresh in Texas under controlled conditions to ensure dense, active cells ready for use.

Well suited for refugiums, zooplankton cultures, and advanced reef systems focused on live food production. Use Chaetoceros calcitrans to strengthen and diversify the nutritional base of your reef.
