Fritz BioDome Ceramic Filter Media 3L
FritzZyme BioDome ceramic filter media is essential for increasing the surface area for nitrifying bacteria to colonize and reduce buildup of toxic ammonia and nitrite. Its compact size and shape allows for more surface area in less volume, while still allowing free water flow through the media reducing buildup and clogging. FritzZyme BioDome have 80-90% porosity and an effective surface area: 2250 m2/L When used in high flow areas of the aquarium, FritzZyme BioDome promotes establishment of nitrifying bacteria like FritzZyme nitrifiers to reduce ammonia and nitrite. When used in low flow areas of the aquarium, FritzZyme BioDome promotes establishment of heterotrophic bacteria, like those found in FritzZyme 360 and 460 to naturally reduce nitrates and phosphates.
Surface Area:
Per dome 75 m2 or 807 ft2
Per 1L bag 2250 m2 or 24218 ft2
Approximately 1.75” x 1.75” x 1.75” each
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

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
