Tropic Marin® Cyo-Control naturally blocks the recurrence of cyanobacteria in the aquarium. After the cyanobacteria have been removed manually, the probiotic bacteria of Tropic Marin® Cyo-Control settle in their place. Once these bacteria have established themselves, they outcompete the cyanobacteria, preventing them from recolonizing the area. The zeolite substrate supports the probiotic bacteria in this process and makes the water extremely clear after a short period of cloudiness.

Reliable cyanobacteria prevention after manual removal.

Purely natural, based on probiotic bacteria and natural zeolite mineral.

Only a few doses required.

Binds pollutants and makes the water extremely clear.

Can be stored without refrigeration.

No antibiotics, no biocides, no toxins

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.
