Crystal Cal Granular Activated Carbon is guaranteed to clear up your cloudy aquarium water overnight. Made specifically for aquarium water filtration, our laboratory-grade activated carbon features a sub-bituminous coal base with optimum pore structure to remove colors, tannins, odors, medications and other common organic waste contaminants.

While most of the carbon sold for fish tanks is actually designed to treat air, Crystal Cal Granular Activated Carbon is washed and steam-activated to treat aquarium water, specifically. Unlike other common carbons or charcoals which can have high levels of contaminants that can leach into water, our carbon has low levels of dust and impurity extractables.

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.
