It is impossible to maintain a healthy, vibrant marine aquarium without also maintaining the proper levels of calcium and alkalinity. Fritz RPM Calcium Buffer System allows aquarists to maintain these two critical components in their proper ionic balance. Unlike other similar products, Fritz Calcium Buffer System

Does not contain unmeasured and unnecessary ions and metals, which unchecked can lead to toxicity in the aquarium. Part 2 is formulated to provide the highest purity calcium, and when used in conjunction with Part 1, along with regular water changes with a high quality salt, will provide the correct ionic balance necessary for healthy and beautiful coral, fish and invertebrates.

Guaranteed Analysis: Calcium (min) 55,000 ppm

Ingredients: Deionized water, calcium chloride

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.
