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.

The process is illustrated A bright idea: Avo features smart LED lighting that is optimised for plant photosynthesis and growth, which leads to clear water. It glows red in the morning, white during the day, and blue at night to look pretty in a room The plants and bacteria work together to create a balanced micro-ecosystem. The harmful ammonia, nitrite and nitrate are removed from the water meaning the water never needs changing.The filtration system is natural and self-maintaining, comprising a moving bed that doesn’t need cleaning. When there is too much light, fish tanks get algae.

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. cheap 55 gallon fish tank hoodIt 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.diy 6 foot fish tank standSo far, £45,000 ($72,669) has been raised out of her £60,000 ($96,892) goal, with 52 days to go.‘cheap 55 gallon fish tank hoodI'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.‘custom fish tanks toledo ohio

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.‘corner fish tank coverI decided I'd design something that takes the stress out of keeping tropical fish and makes fish keeping simple, beautiful and above all enjoyable.‘fish tank filter electric billAvo 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'One of the main reasons people get rid of or never purchase a fish tank is because of the odor.

Thank God my 58 gallon tank (220litre) has never once emitted an odor. I keep my tank clean and avoid anything that could potentially make my water smell poorly. No matter what the pet store salesman may tell you, don’t overpopulate your fish tank. The general rule is one inch of fish per gallon of water, but remember to keep in mind the size the fish will be when it’s full grown. If your fish tank is only 20 gallons, that means you can keep 5 fishes that is 4 gallons per fish. Though you can keep some more if they are very tiny such as small tetra species. Just remember that although fish like Oscars are purchased when they are about 2 inches long, they can get up to 6inches or more after living for just one year. I have Angle and Discus fishes which grow up-to 7-8 inches, so I keep around 10 fishes in my tank. Overpopulating your fish tank leads to more fish pooping, which leads to more waste on the bottom of the tank. Don’t rely on Plecos cause Plecos don’t eat fish waste – that’s what a gravel vacuum is for.

If you overpopulate your tank, it is bound to smell. One of the most important aspects of aquarium care is cleaning the aquarium. For the best success, I recommend doing a 10-20% water change every week, using a gravel vacuum very well once a month (draining about 30-40% of the water), and cleaning algae daily. If you never clean or maintain your aquarium, this is the reason it smells. Even with fish that help clean things up, you still need to take responsibility and clean your tank. Clean your tank glass with soft clean cotton cloth which will reduce Algea growth and use a good quality shiffon vaccum and clean the gravel in 15 days. Most carbon or sponge filters that you purchase at pet stores only come with one filter. Filters should be cleaned every once in a while and replaced after a few months. Canister filters should be taken apart and cleaned every six months. If your fish tank has no filtration at all, then there should be no question of what is making your water cloudy and smelly.

When I purchased my first aquarium, I bought a 20 gallon tank, a sponge filter and a air motor with air stone, this is a good starter tank. Though it is no longer with me, initially some of my fishes got killed, due to lack of knowledge. Now I am using a AQUA ONE 1000 canister filter and a small sponge filter for my tank. Clean the canister in 3 months approx and the sponge one in every 10 days. If you look at your water and notice that it has a green hue to it, this means that you have algae growing. Algae can be reversed by buying chemicals from your local pet store and buying algae-eating fish. Algae is caused by improper filtration and excess sunlight. If your tank is near a window and gets more than six hours of direct sunlight a day, then you are going to get algae. Brown algae is a common occurrence in a newly set up aquarium and I hate this personally. It is generally caused by too little light, an excess of silicates, an abundance of nutrients, and too little oxygen.

Silicates can build up through tap water that is high in chlorine, and silicates that leech from some types of substrates. Cure: Wipe off surfaces & vacuum gravel well. Use silicate adsorbing resin in the filter. Stock a small size Plecos or several Otocinclus. Prevention: Use anti-chlorinated water. This type of algae does not adhere strongly to the tank surfaces, and is easily wiped away. Vacuuming the gravel with a siphon will quickly remove coatings from the substrate. Increasing the lighting will inhibit re-growth of brown algae. As a new tank matures brown algae is often eliminated naturally by plants and green algae competing for nutrients. Some sucker-mouth catfish will readily eat brown algae, most notably Otocinclus. If the problem is due to high silicates in the water, and the brown algae persists, a special silicate absorbing resin can be used in the filter. If you have made it this far on the list and none of the above reasons apply to your tank, then you could have dead organisms in your tank.
