Reef Essential® Signature Series™

Eleven elements, dosed exactly where your tank needs them.

Signature Series is for aquarists who want to correct one specific element rather than a broad-spectrum blend — typically in response to an ICP test result showing something running low or out of balance. Each product is organized by its periodic table grouping, so related elements are easy to find and reason about together.

Built for ICP-guided dosing. Signature Series is the precision layer on top of Steps 3–5 — use it when regular ICP testing shows a specific element running low, rather than as your baseline dosing routine. Combined with regular testing, it's how you fine-tune a tank that's already following the Reef Essential® system.

Each element is dosed on its own, so you can correct exactly what your test results show without moving other parameters you don't need to touch.

Not sure which element you need?

The dosing app calculates exact amounts once you know your ICP results.
