S58 Jellyfish Aquarium

Complete Step-by-Step Guide

Setting up a 15 gallon jellyfish tank (also known as a 58 liter jellyfish tank) is an exciting and rewarding process. At JellyfishTank.net, we specialize in premium Cherry jellyfish tanks designed for both beginners and enthusiasts. Whether you're starting with our popular Cherry series 15-gallon model or a similar round or square 58-liter system, this detailed guide will walk you through every step to ensure a safe, stable environment for your jellyfish.

Our Cherry jellyfish tanks are engineered for gentle, kreisel-style flow perfect for delicate jellyfish species like Moon Jellies, Flame Jellies, or Blue Jellies. Follow along and you'll have a thriving 15 gallon jellyfish tank ready in no time.

Step 1: Choose the Perfect Location for Your 15 Gallon Jellyfish Tank

Before unboxing anything, find a strong, sturdy, level surface for your 58 liter jellyfish tank. A dedicated aquarium stand, sturdy bookshelf, or reinforced table works great. The tank weighs approximately 150–180 lbs when fully filled, so stability is critical.

• Place it away from direct sunlight (to prevent algae issues).
• Keep it in a room with stable temperatures (ideally 68–78°F / 20–26°C).
• Ensure easy access to a power outlet and a nearby water source for maintenance.
• Avoid high-traffic areas where vibrations or bumps could disturb your jellyfish.

Pro Tip: For the best viewing experience with your Cherry jellyfish tank, position it at eye level in a quiet corner of your home or office.

Step 2: Unbox and Prepare Your Components

Carefully unbox your new 15 gallon jellyfish tank. Lay out all parts:

• The main acrylic tank body
• LED lighting system
• Spray bar and tubing
• Super Start biological media (with string)
• Black filter sponge
• Power supply and flow valve
• Any additional accessories (e.g., feeding tools or test kits)

Remove the protective film from the acrylic surfaces and inspect for any shipping damage. Set the light aside for now.

Step 3: Install the Biological Filtration Media (Super Start)

Your Cherry jellyfish tank comes with premium Super Start live biological media to kickstart the nitrogen cycle.

• If you're not setting up immediately, store the sealed Super Start bag in your refrigerator for up to two weeks.
• Remove the media from its bag.
• Detach the tube from the spray bar.
• Hold the media by the attached string and tuck it neatly into the left filtration compartment.
• Loop the string securely around the spray bar fitting.
• Reattach the hose and ensure all connections are snug.

Important: Once installed, the Super Start media does not need regular removal or cleaning — it will continue supporting beneficial bacteria long-term. This step is crucial for a healthy 15 gallon jellyfish tank.

Step 4: Prepare and Install the Filter Sponge

• Rinse the black filter sponge thoroughly under cool tap water for several minutes to remove any dust or manufacturing residue. Avoid soap.
• Tuck the sponge neatly into the left side filtration area of your 58 liter jellyfish tank, next to the biological media. It should fit snugly without blocking water flow.

This mechanical filtration helps trap debris while maintaining the gentle currents your jellyfish need.

Step 5: Fill Your 15 Gallon Jellyfish Tank with Saltwater

Now it's time to mix and add saltwater. For best results with your Cherry jellyfish tank:

• Use a high-quality salt mix designed for jellyfish or invertebrates (e.g., Instant Ocean or a similar reef-grade mix).
• Aim for a specific gravity of 1.020–1.025.
• We strongly recommend purchasing pre-mixed saltwater from a local aquarium store (often ~$1 per gallon) for your first fill to ensure perfect parameters.

Use a pump or siphon to gently fill the tank. Fill until the water level sits just below the two baffles at the top. This creates the proper overflow and circulation for a 15 gallon jellyfish tank.

Pro Setup Tip: If mixing your own, use an automated mixing station or let it aerate for 24 hours before use.

Step 6: Proper Electrical Setup and Drip Loop Safety

Safety first with any aquarium:

• Create a drip loop with the power cord: Hang the cord below the outlet level so any drips fall to the floor instead of into the socket.
• Plug in the power supply directly to your Cherry jellyfish tank.
• Set the flow valve to approximately halfway initially. You can fine-tune this later based on how your jellyfish respond.

Test the system: The water should circulate in a smooth, gentle, circular pattern ideal for jellyfish.

Step 7: Lighting Installation and Initial Cycling

• Install the LED light on top of your 15 gallon jellyfish tank.
• Turn on the light on a timer (typically 8–12 hours per day to mimic natural daylight).

The Cycling Process (Critical for Success): Even with Super Start live bacteria, your new 58 liter jellyfish tank needs time to fully cycle. This usually takes about 7 days.

• During cycling, monitor ammonia and nitrite levels daily or every few days.
• Take a water sample to your local fish store for free testing, or use a reliable home test kit.
• Do not add jellyfish until ammonia and nitrites read 0 ppm and nitrates are low/stable.

Patience here prevents stress or loss of your jellyfish.

Step 8: Acclimating and Adding Your Jellyfish

Once the tank has cycled successfully:

• Order juvenile or adult jellyfish from a reputable supplier (we can help recommend partners at JellyfishTank.net).
• Acclimate slowly using the drip method over 30–60 minutes.
• Start with a small group in your Cherry jellyfish tank — species like Flame Jellies will gradually develop their vibrant colors as they grow.

Observe their behavior: Healthy jellyfish pulse gracefully and stay suspended in the water column.

Maintenance Tips for Your 15 Gallon Jellyfish Tank

• Perform 10–20% weekly water changes with pre-mixed saltwater.
• Feed appropriate jellyfish food (e.g., brine shrimp, rotifers, or specialized jelly feeds) 1–2 times daily.
• Keep flow gentle — adjust the valve as needed.
• Clean the exterior acrylic with a soft cloth and aquarium-safe cleaner.
• Monitor temperature, salinity, and pH regularly.

Caring for Moon Jellyfish in Your 15 Gallon Jellyfish Tank (58 Liter Jellyfish Tank)

Moon jellyfish (Aurelia aurita) are among the most popular and beautiful species for home aquariums, thanks to their graceful, pulsing movement and translucent bells. They thrive beautifully in a well-maintained Cherry 15 gallon jellyfish tank or similar 58 liter jellyfish tank when you follow proper care guidelines. Here’s everything you need to know about water parameters, feeding, and maintenance.

Water Parameters for Moon Jellyfish

Moon jellyfish are sensitive to water quality, so stability is key in your 15 gallon jellyfish tank:

• Temperature: 68–75°F (20–24°C). Use a chiller connected to the refrigerator socket on your Cherry tank to keep water cool and consistent.
• Salinity / Specific Gravity: 1.020–1.025. Test regularly with a reliable hydrometer or refractometer.
• pH: 8.1–8.4
• Ammonia & Nitrite: Must always be 0 ppm
• Nitrates: Keep below 10–20 ppm through regular water changes
• Alkalinity: 8–12 dKH

Perform 10–20% water changes weekly using pre-mixed saltwater matching your tank’s parameters. The integrated filtration system in the Cherry jellyfish tank helps, but consistent monitoring with test kits is essential.

Feeding Moon Jellyfish

Feed your moon jellyfish daily or every other day. They primarily consume small zooplankton:

• Recommended Foods: Enriched baby brine shrimp, rotifers, or commercial jellyfish feeds (e.g., Reef Nutrition’s Reef-Roids or similar).
• Feeding Method: Broadcast food gently into the gentle circular flow so it drifts naturally toward the jellyfish. Feed small amounts that they can consume within 30–60 minutes.
• Quantity: 1–2 times per day for juveniles; adjust based on size and activity level. Overfeeding leads to poor water quality.

Cleaning Uneaten Food and Tank Maintenance

Uneaten food can quickly degrade water quality in a 58 liter jellyfish tank, so prompt removal is critical:

• After feeding, use a turkey baster or gentle siphon to remove leftover particles from the bottom and filtration areas.
• The black filter sponge and biological media in your Cherry tank will trap some debris — rinse the sponge gently in tank water (not tap water) during water changes if needed.
• Keep the circular flow running 24/7 to prevent stagnation.
• Inspect your moon jellyfish daily for signs of stress (shrinking bells, irregular pulsing) which often indicate water issues or overfeeding.

With diligent care, moon jellyfish can live 1–2 years or longer in a properly maintained Cherry 15 gallon jellyfish tank. Their mesmerizing display makes the effort worthwhile.
