Biologically Ideal Strontium Supplement for Reef Aquariums

Replenish essential strontium

Does not disrupt ionic balance

Natural substances are formed

No chelates, phosphates, or nitrates

A sufficient supply of strontium is as essential for the growth and well-being of reef-building corals as calcium. In the reef aquarium, the strontium concentration can drop rapidly to low values due to biological processes, precipitation and incorporation into the limestone skeleton.

Tropic Marin Bio-Strontium utilizes the natural environment in the aquarium and delivers strontium and carbon dioxide in a natural, biologically-available, powdered form and thus supports the healthy development of coral. Bio-Strontium

Does not disturb the ionic balance in contrast to the single addition of strontium 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.
