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

How do I fit a heater in my HALO 15 litre?

A heater can be easily fitted. First you will need to remove the notch out of the evaporation tray. This can be carefully done with a craft knife. Once removed your cable can route through the lid. At the point where it goes through the evaporation tray and the notch on the lid rim, you will need to fold the cable as it is a tight fit. This is to prevent evaporation.

Shown in this photo is how the cable routes.

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 do I have to change the filter cartridge?

Die Filterpatrone arbeitet wie ein Abfalleimer. Nach einer gewissen Zeit ist er voll. Indem Sie die Patrone regelmäßig auswechseln, entfernen Sie alles, was sie aus dem Aquarium aufgenommen hat, so wie Sie auch Ihren Müll herausbringen, damit er abgeholt werden kann. Für eine optimale Filterung sollte die Filterpatrone alle vier bis sechs Wochen ausgetauscht werden. Im biOrb 105 l/28 GAL muss der Filter alle vier Wochen ausgetauscht werden.

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.
