Tropic Marin Reef Actif 60g
Tropic Marin Reef Actif 60g
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.

Feeding & Diet
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
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.

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
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.
