FAQ
What size biOrb is best for a single Betta fish?+
The biOrb Mini (10 litre) is generally recommended for a solitary Betta. This smaller volume provides ample space for the fish to swim and prevents overstocking, which can lead to poor water quality.
Do I need a separate filter for my biOrb?+
While biOrbs have an integrated air stone for gentle aeration, a small internal filter is highly recommended. This will help maintain excellent water clarity and remove any accumulated waste effectively.
What type of heater should I use with my biOrb?+
A submersible aquarium heater specifically designed for small tanks is essential to maintain stable temperatures. Choose a heater with adjustable temperature settings to suit your fish’s specific needs – typically 24-28°C.
How often should I clean my biOrb?+
Regular partial water changes are vital, aiming for around 20-30% every two weeks. This removes accumulated nitrates and replenishes essential minerals for your fish.
What substrate is best for a biOrb?+
Fine gravel or sand is ideal for biOrbs as it provides surface area for beneficial bacteria to colonise, crucial for the nitrogen cycle. Avoid larger substrates that could bury the fish’s eyes.
Can I add live plants to my biOrb?+
Yes, you can! However, consider the size of your biOrb and choose small, slow-growing plant varieties such as Java Moss or Anubias. Provide adequate lighting for healthy growth.
What kind of fish are suitable for a biOrb 45?+
The larger biOrb 45 is well-suited to smaller community fish like Neons, Corydoras and small Tetras. Avoid stocking overly large or aggressive species.
How do I set up my biOrb?+
Start by rinsing the tank thoroughly with dechlorinated water. Add substrate, plants (if using), and then carefully fill with water. Install your heater and filter before introducing your fish.
Are biOrbs suitable for saltwater aquariums?+
No, biOrbs are designed specifically for freshwater aquariums. The acrylic is not compatible with the higher salinity levels required for saltwater environments.
What accessories are available for biOrbs?+
A wide range of accessories are available on Amazon UK including LED lighting systems, air pumps, decorative ornaments and specialized fish food tailored to biOrb ecosystems.
