Desktop Jellyfish Tank O2 Liter

This desktop jellyfish tank is specially engineered with a circular kreisel-style flow that keeps delicate jellyfish safely suspended and away from the filtration intake. The hidden outer-circle filtration chamber houses a biological filter with ceramic bio balls that efficiently break down toxins, while an adjustable return stream provides gentle currents and strong aeration. The result is a low-maintenance, high-performance system ideal for experienced keepers who want a true miniature live jellyfish display on their desk.

Important Considerations for the O2 Desktop Jellyfish Aquarium

Please note that due to its small water volume, the O2 is one of the more demanding desktop jellyfish tanks. It requires very consistent care and stable conditions. We recommend it primarily for experienced jellyfish keepers. Beginners will have much greater success and easier maintenance with larger models such as the C8, Orbit 18, or Alpha 22. The O2 shines brightest when housing petite jellyfish species rather than larger ones.

Recommended Jellyfish Species for Your Desktop Jellyfish Tank

The O2 Mini Jellyfish Aquarium is particularly well-suited for small, delicate species including:

• Eirene lactoides
• Leuckartiara octona

While some advanced keepers successfully house small moon jellyfish in the O2, larger tanks are generally preferred for moon jellies due to their size and activity level. Always research the specific needs of your chosen species before purchasing.

Complete Setup Guide for Your Desktop Jellyfish Aquarium

Setting up the O2 desktop jellyfish tank is straightforward but requires attention to detail:

1. Choose the Perfect Location Place your O2 on a stable, level desktop or surface away from direct sunlight, windows, heaters, vents, or high-traffic areas. Stable room temperature is critical for this small-volume aquarium.
2. Prepare Saltwater Use only RO (reverse osmosis) or distilled water mixed with high-quality marine salt. Target salinity of 30–34 ppt (specific gravity 1.023–1.026). Mix thoroughly and allow it to aerate for 24 hours. Test parameters before filling.
3. Assemble and Cycle the Tank Install the filtration media and fill the O2 with prepared saltwater. Run the system continuously for 1–3 weeks to establish beneficial bacteria. Monitor ammonia and nitrite levels until they read zero consistently.
4. Add Lighting and Test Flow Activate the beautiful RGB LEDs using the convenient touch controls. Adjust the flow valve to create gentle circular currents suitable for your jellyfish.
5. Acclimate Your Jellyfish Float the bag in the tank for 20–30 minutes, then gradually mix tank water into the bag over another 30–60 minutes before gently releasing them.

Moon Jellyfish Care in a Desktop Jellyfish Tank

Although the O2 is best for petite species, here is essential guidance if you are an experienced keeper housing small moon jellyfish:

• Feeding: Feed 1–2 times daily with specialized jellyfish food or freshly hatched baby brine shrimp. Turn off or reduce flow during feeding so food stays suspended. Use a pipette for precise delivery and remove uneaten food promptly.
• Water Changes: Perform 20–30% water changes every 3–5 days (more frequently than in larger tanks) using pre-mixed, temperature-matched saltwater. Consistency is key in small desktop jellyfish aquariums.
• Water Parameters:
  • Temperature: 68–75°F (20–24°C)
  • Salinity: 30–34 ppt
  • pH: 8.0–8.4
  • Ammonia/Nitrite: 0 ppm
  • Nitrates: Below 10–15 ppm
• Lighting: Use the color-changing LEDs sparingly or on low intensity to avoid algae growth while still enjoying the stunning visual effects.
• Maintenance: Clean the acrylic gently with the included tools. Monitor flow and adjust as needed to keep jellyfish drifting comfortably.

With diligent care, your O2 desktop jellyfish tank can provide months of enjoyment and relaxation.
