The Premium Saltwater Reef Tank Kit
The most beautiful and most demanding tank in the hobby.
A reef aquarium is the pinnacle of fishkeeping. Coral — living animals that photosynthesize — requires near-perfect water chemistry, intense lighting, and strong flow. Done right, a reef tank is the most beautiful living display you can own. Done wrong, it's an expensive education.
The Coralife BioCube 32 is an all-in-one reef system with filtration, pump, and LED lighting built in — the most beginner-accessible reef tank available without sacrificing capability. A protein skimmer removes organic waste before it breaks down, which is critical for the water quality coral demands. The Instant Ocean salt mix and refractometer allow you to mix saltwater at precisely the right salinity (1.025-1.026 specific gravity).
This is a hobby that rewards research. Join a local reef club before starting — the community knowledge is invaluable.

Instant Ocean Sea Salt (200-Gallon Mix)
The most trusted reef salt mix for decades. Formulated with the exact mineral composition of natural ocean water — tested and verified by marine biologists. Used by public aquariums worldwide.
Milwaukee MA887 Digital Refractometer
Precise salinity measurement is non-negotiable in a reef tank. Coral and fish tolerate a very narrow salinity range (1.025-1.026). A digital refractometer provides the accuracy that swing-arm hydrometers cannot.
