For treating aquarium water between water changes.

Tropic Marin® Reef Actif is made up of a mixture of natural organic substances of predominantly marine origin. The biopolymers in Tropic Marin® Reef Actif bind excess nutrients and other pollutants and cause them to be degraded by specialized marine microorganisms. This promotes a natural marine microbiology in the aquarium and keeps the water extremely clear.

By activating the microflora, numerous vitamins and other vital substances are added to the water in a completely natural way. Corals and bivalves open better and reveal all their rich coloring. The fish also benefit from the stable bacterial flora and the prebiotic effect – they develop robustly and show their vitality through flawless coloring and natural behavior.

Add one level measuring spoon of Tropic Marin® Reef Actif to 500 liters/132 US gallons of aquarium water each week. Stir the powder into a small amount of aquarium water and then add it to the aquarium to distribute it as finely as possible.

Maximum dosage: One measuring spoon per 500 liters/132 US gallons of aquarium water three times a week.

Feeding & Diet

An opportunistic omnivore, the Pithos Crab will scavenge detritus, uneaten food, and algae — making it a natural cleanup crew member. Supplement with small meaty foods like mysis shrimp or pellets 2–3x per week if natural food sources are limited.

Care & Water Parameters

The Pithos Crab thrives in stable, well-maintained reef conditions. Target parameters: temperature 72–78°F, salinity 1.025–1.026 SG, pH 8.1–8.4, and alkalinity 8–12 dKH. A mature, established tank of at least 20 gallons is recommended.

Reef & Tank Compatibility

Generally considered reef-safe. The Pithos Crab coexists well with most corals and peaceful fish. Use caution with very small invertebrates or slow-moving tankmates. Provide ample rockwork and hiding spots to reduce territorial behavior.

Size & Growth

Pithos Crabs are typically shipped at 0.5–1.5 inches. They are slow-growing and generally remain small, making them well-suited for nano and mid-size reef systems.
