Scraping muck and slime from the side of a tank, and continually cloudy water, annoys many fish owners.But now a young designer has created a fish tank that she claims never needs cleaning, the water never needs changing, and owners can save money bu never needing to replace the filter. The spherical tank only requires an owner to top up the water occasionally – and to feed the fish. Cleaning up: A young designer has created a fish tank that she claims never needs cleaning, the water changing, or a new filter. The spherical tank, called Avo, (pictured) only requires an owner to top up the water occasionally – and to feed the fish.Suzy Shelley, a graduate from Loughborough University, created the 15-litre tank, which is fitted with technology that enables fish, plants and bacteria 'to work together to create a balanced ecosystem'.The tank, called Avo, has a self-cleaning filter that ‘never needs replacing’.A continually-moving bed recycles older bacteria into plant food, creating space for new bacteria to grow.‘

Harmful ammonia, nitrite and nitrate are naturally removed from the water, meaning the water never needs changing,’ according to the company, called Noux.

Avo's lighting is plant-specific, providing the wavelengths that the plants need to photosynthesise and grow, making sure they are cleaning the water efficiently. It produces wavelengths of light that our human eyes can't detect.The light moves around the tank and is magnetic, so can be detached to access the fish and plants easily. Water is heated at 27°C (80.6°F) - the perfect temperature for tropical fish.

The heating elements are positioned to create convection currents which help the nutrients reach the roots of plants.Seven plant pots slot into place in the filter system to make them easy for owners to lift out and trim. The tank holds three-and-a-half gallons of water (15 litres). It is available to pre-order from £150 ($242). Avo features smart LED lighting that is optimised for plant photosynthesis and growth, which leads to clear water.The lighting is soft red in the morning, white during the day, and blue in the evening.The tank is designed for tropical fish with a constant water temperature of  27°C (80.6°F).The plants are housed in seven trays so they can be easily maintained and moved around to change the look of the tank. It has taken Ms Shelley over four years to develop the tank, which is now raising funds on crowd funding website, Kickstarter.Avo can be pre-ordered from £150 ($242) plus shipping and the tank is due to be shipped in July next year.So far, £45,000 ($72,669) has been raised out of her £60,000 ($96,892) goal, with 52 days to go.‘

I've always kept fish and it was a steep learning curve in the early days - trying to maintain a tank properly, making sure my fish were healthy and had a clean tank,’ Ms Shelley said.‘Fish keeping isn't as easy most people think…there's important bacteria in the tank that need to be maintained, plus there's the weekly water changes and smelly filter cleaning needed to maintain a healthy tank,’ she wrote on Avo’s Kickstarter page.‘I decided I'd design something that takes the stress out of keeping tropical fish and makes fish keeping simple, beautiful and above all enjoyable.‘Avo is packed full of technology and clever design features that make it really, really easy to keep fish.’ Suzy Shelley (pictured), a graduate from Loughborough University, created the 15-litre tank, which is packed with technology enabling fish, plants and bacteria 'to work together to create a balanced ecosystem'The great thing about keeping goldfish is they are pretty easy maintenance which is why they are such a great choice as first pets for kids.

However, this does not mean fish can be put in their tanks and then forgotten, because their environment still needs to be kept as clean as possible for them to remain healthy. If the water is crystal clear you can enjoy seeing the fish swimming around which is extremely relaxing. If the water is too murky, you won't be able to see a thing! The water won't stay very clear if there's no filtration system in the tank. It doesn't take long for debris and dirt to mount up and it can really spoil things for your fish. A dirty environment is not very nice for them to swim around in because the majority of the dirt would be made up of their poop. However, just because you have a filter in a tank doesn't mean you can then just forget about things, because filters too need to be kept clean and regularly checked or they won't work properly which could make water clarity that much worse. It's all too easy to give fish too much food which is why it's important for any uneaten food to be taken out.

It tends to float around in the tank and just waiting 10 or minutes before scooping it up with a net will help keep things a lot cleaner, and clearer. As a rule of thumb, fish should be fed little and often which not only prevents any uneaten food from laying at the bottom of the tank where it starts to rot, but less waste means less expense too. If you have just got a new tank, the chances are the water is looking a little cloudy which is commonly known as “new tank syndrome”. The reason why the water is a milky colour is due to a bacterial bloom, but the good news is you can quite safely change a little of the water on a regular basis without harming your fish in order to get rid of the problem. It's something that tends to happen in new tanks as the water settles and the right chemical balance is achieved. You can change a bit of the water twice a week and pretty soon, the cloudiness will disappear altogether. Algae causes water to have a green tinge to it and although most fish tanks have some algae in them which fish tend to nibble at it every now and again which means when there's only a little, it should not be too much of a problem.

The trick is to keep algae growth under control and not let it take over. If there's too much light on a tank it can accelerate the growth which can really spoil the effect and clarity of the water, not to mention it's not a very nice environment for fish to swim around in. You should avoid placing your fish tank too near a window and to turn lights on for around 10 to 12 hours a day at most. Using chemicals is an easy route to take when it comes to keeping water in a fish tank clear and as a last resort there are some very effective water treatments available which are very safe to use. Chemical flocculants are a good option because they bind tiny particles of dirt together which makes it a lot easier to scoop the larger lumps out of the tank using a fish net. The rule of thumb is “a clean tank is a healthy one” which means regular maintenance and cleaning is essential. As with most things, prevention is always so much easier than cure so by keeping on top of things, the water in your fish tank should remain crystal clear which means your fish live in a lovely environment which ensure they stay nice and healthy.
