Fritz Pro Aquatics Ammonium Chloride 500g
In most aquariums, the biological cycle is started by introducing fish into the aquarium. The fish excrete ammonia which acts as a food source for nitrifying bacteria. Nitrifying bacteria convert ammonia into nitrite and then nitrite into nitrate. Fritz ammonium chloride (nh4cl) can be used as a source of ammonia to initiate the growth of nitrifying bacteria without the presence of animal life. Fish should not be present while using ammonium chloride.

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.
Reef & Tank Compatibility
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
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.
