Why reef keepers choose it

Batch-tracked live phyto with a cleaner path to reorder.

Reef hobbyists want consistency, clean handling, and a product they can reorder without guesswork.

Batch tracked

Every production run is positioned as a controlled, traceable batch instead of anonymous commodity product.

Packed cold

Cold-chain minded packing helps protect refrigerated live culture quality during transit.

Routine friendly

Clear size options and dosing guidance make it easier to build a repeatable reef-feeding workflow.

Clean storefront

Straightforward product pages and checkout make reordering easier.

Dosing estimator
Start with system volume, then adjust to response.

A practical starting point for refrigerated live phytoplankton is to begin modestly, build consistency, and scale up only as your reef shows demand.

75 gal

Begin conservatively. Monitor nutrient load, skimmer behavior, water clarity, and livestock response before increasing daily volume.
