How do I change the filter?

Changing the filter is very easy and you do not need to remove the fish to carry out the filter change. All you need is a service kit for your biorb and it comes supplied with a new filter, water treatments for the partial water change and a cleaning pad so that you can wipe around the inside of the aquarium.

The service kit is also supplied with instructions on how to change the filter if you are unsure.

Why has the water turned green?

Algae needs sunlight and nutrients in order to grow. Too much daylight, especially during the summer months when the days are longer and warmer, will cause algae to thrive. Excess nutrients in the water, from over feeding for example, will also cause algae problems. It is easier to prevent algae than to remove it once it has become a problem.

Why is the pump noisy?

Noise from the pump is usually caused by vibration against the surface it is on. Place the pump on a softer surface like a mouse mat or hang the pump up. Make sure the airline is pushed into the air pump as far as it will go. 

If the pump is still noisy and is within the warranty period you can return to your retailer for a warranty exchange.

Also the addition of a small air line clamp to the air line will help.

Air line clamps can be attached to the air line to give control of air flow.

You can tighten the clamp to reduce flow and undo to increase flow.

Care should be taken to ensure the aquarium still has a good flow of air.

Why do I have to change the filter cartridge?

The filter cartridge works like a waste bin, after a time this will become ‘full'. By regularly changing the cartridge everything it has absorbed is removed from the aquarium, just like taking your household waste bin out to be collected. For optimum filtration the filter cartridge should be replaced every four to six weeks. For biOrb 105L/28GAL replacing the filter every four weeks is required.

What should I do if a fish dies?

If a fish dies you should remove it from the aquarium immediately, if left in the aquarium it will pollute the water. You should try to establish why the fish died. Make a note of anything that is abnormal. Take a sample of your aquarium water to a good aquatics retailer for testing and advice.

Why do I need to add fish gradually?

When the fish goes to the toilet ammonia is created, this can be deadly to fish. The bacteria convert the toxic ammonia into nitrite and then a safer substance called nitrate. When a fish is added the level of ammonia and nitrite will rise sharply. As the filter bacteria catch up they will keep the ammonia and nitrite to a safe level and the safer nitrate will steadily rise. This process is called the ‘cycle’ and will take about 28 days for one small goldfish. This is potentially a risky time for the fish and the level of ammonia should be minimised by introducing a small fish and not feeding too much. Even so, some fish may not cope with life in very new aquariums. It is essential that fish are introduced gradually at a rate of one small fish every 28 days.

How does a biOrb filter work?

Biological, Mechanical and Chemical.

Clean water flows vigorously up the bubble tube in the centre of your biOrb. As it breaks the waters surface it keeps the gases in equilibrium with the air above the water surface.

The circular flow of water then collects any fish waste on its way down.

It draws the waste through the ceramic media where the natural biological filtration absorbs some toxins. The freshly oxygenated water also feeds the bacteria.

Any remaining waste is trapped in the sponge cartridge. The water then passes through resin particles and natural stabilisers to remove toxic substances and keep the pH levels constant.

The clean water is then oxygenated as it flows back up the bubble tube to repeat the cycle.

How do I change my biOrb filter?

Changing the filter is easy.

Switch off the pump. Reach into your biOrb and turn the bubble tube a quarter turn to release it. Then simply lift out the entire filter cartridge. Another quarter turn removes the filter which contains all the waste. Twist on a new filter. Place back into your biOrb, switch the pump on and you’re done.

How do I recycle the electrical components from my biOrb?

What is WEEE?
The Waste Electrical or Electronic Equipment (WEEE) Directive requires countries to maximise separate collection and environmentally friendly processing of these items. In the UK, distributors (including retailers) must provide a system which allows all customers buying new electrical equipment the opportunity to recycle their old items free of charge. Those establishing their own take-back scheme must as a minimum offer all customers buying new electrical equipment free take back of their old electricals on a like-for-like basis.

Where is your local recycling centre?
Find more information on WEEE recycling and locate your local recycling centre at www.recyclenow.com
