Ciano Aqua 20 Classic Aquarium - Black

This 17-litre tank is best suited for very small cold-water fish like a small group of White Cloud Mountain Minnows, or a small colony of freshwater shrimp or snails. It is not suitable for common goldfish or tropical fish unless you add a heater and select very small tropical species.

You should perform a 20-25% partial water change weekly. The filter media should be rinsed in old tank water every 2-4 weeks, and mechanical media (like filter floss) replaced monthly. The tank glass can be cleaned as needed to remove algae.

The Ciano Aqua 20 Classic is designed for cold water setups, so a heater is not strictly necessary for common cold-water fish. However, if you wish to keep tropical fish, you would need to purchase and install an appropriate aquarium heater.

The integrated filter features three-stage filtration, typically using mechanical media (like sponges or filter floss) for debris removal and biological media (like ceramic rings or bio-balls) to house beneficial bacteria. Specific media types may vary, but standard aquarium filter media is generally compatible for replacement.

Yes, you can keep live plants in the Ciano Aqua 20 Classic. However, you may need to add a dedicated aquarium light as one is not included, and consider a suitable substrate for plant roots. Choose low-light, easy-care plant species for best results.

Aquarium cycling is the process of establishing beneficial bacteria in your tank's filter and substrate. These bacteria convert toxic fish waste (ammonia and nitrite) into less harmful nitrates. Cycling is crucial because it creates a stable and healthy environment for your fish, preventing them from being poisoned by their own waste. It typically takes several weeks before fish can be safely added.

Perform a 25% water change. Check if you are overfeeding and reduce food if necessary. Ensure the filter is running properly and its media is not clogged. If new, allow time for the nitrogen cycle to establish.

Unplug the filter and remove it. Check for blockages in the intake tube or impeller. Rinse the filter media in old aquarium water (never tap water) to remove debris. Reassemble and restart.

Immediately test water parameters (ammonia, nitrite, nitrate, pH). Perform a 50% water change if ammonia or nitrite are detected. Ensure water temperature is stable and appropriate for cold-water fish. Avoid overstocking.

Reduce the amount of light the aquarium receives (e.g., limit lighting period to 8-10 hours, move away from direct sunlight). Reduce feeding amounts. Increase frequency of water changes and physically remove algae during maintenance.

Check the filter pump for proper seating and ensure the impeller is clean and unobstructed. Make sure the water level is adequate, as low water can cause splashing or air intake noise.
