Don’t leave Laptop Batteries in direct sunlight

Posted on by admin

PolyPlus is currently testing lithium metal-seawater batteries in conjunction with the Monterey Bay Aquarium Research Institute to determine whether they can withstand real working conditions. One concern is that microorganisms in the ocean will grow on the batteries’ surface and impair their operation, although preliminary tests have produced good results.

The single-use batteries made by the company employ a piece of lithium metal about two centimeters squared and three millimeters thick; they have a storage capacity close to that of the lithium-ion batteries in today’s laptops at one-fifth the weight. The company has partnered with battery manufacturer Quallion to produce batteries based on PolyPlus’s electrode designs and will make batteries under contract for an undisclosed government agency. Quallion says that lithium-metal electrodes can be processed using much of the infrastructure already in place for making lithium-ion batteries. “Certain precautions are needed to handle the material, but there are no tricks to it,” says Beach.

When the lithium-metal electrode is placed in water, lithium ions leak out and react with oxygen dissolved in the water or with the water itself. To make a lithium metal-air battery, the device is fitted with a gas-diffusion electrode similar to those used for zinc metal-air hearing-aid batteries. When the battery is switched on, the electrode draws in oxygen through the membrane to react with the lithium ions. But unlike hearing-aid batteries, these devices won’t self-discharge over time. “You can leave the battery on the shelf for months and expect it to work because the membrane protects it,” says Visco. And because they’re based on high-energy lithium metal, these batteries last much longer and are more lighter than zinc-air batteries.

Transform Your Tank With Stunning Aquarium Backgrounds

Posted on by admin

Fish tank backgrounds are an often overlooked but important addition to an aquarium or tank. Many people purchase their aquarium, fish, filter and accessories, and are keen to get the set-up complete and see their fish swimming around as soon as possible. Because they are not essential to the survival of the fish, tank backgrounds tend to be overlooked or forgotten in the excitement of the purchase.

But one of the biggest benefits of having an aquarium or tank, rather than a small fish bowl, is that they give you the chance to give the environment some character. The aquarium can provide an eye-catching focal point and create a calming atmosphere, particularly when lit up at night. To make the most of this, it makes sense to invest in a quality aquarium background.

High quality 3D fish tank backgrounds are an affordable way to transform a tank. They enhance not only the surroundings for the fish, but the appearance of your room as a whole. They even have unique health benefits for your fish.

Some aquarium backgrounds are designed to reflect genuine underwater seascapes, based on beautiful thriving habitats such as the coral reefs of the Galapagos Islands. The backgrounds come in a choice of styles and sizes. Even if you cant find one with the exact dimensions to fit your fish tank, fear not; the backgrounds can be easily cut to size with nothing more than a pair of household scissors.

Of course, any aquarium background is going to give your fish something to look at beyond the usual rock-pebbles-reflection routine, and, as far youre concerned, will add exotic ambience to any room. But a 3D aquarium background offers a whole lot more than mere decoration. Suitable for cold, tropical or marine fish, 3D fish tank backgrounds have a reticulated open cell foam which is hand carved and decorated with pumice stone and plastic, life-like plants. The foam is used to provide a better water quality in the tank; it allows the water to move through it, circulating the natural thermoclines (hot and cold water) in the aquarium. In addition to this, 3D aquarium backgrounds collect healthy bacteria on their protruding surfaces. Your fish need to discard old scales periodically in order to remain healthy. To this end, they can rub against the rough surface of the backgrounds and thus maintain their streamlined form.

Fish tank backgrounds are easily installed with an aquarium-safe sealant, available from fish tank background suppliers. They can be fixed when purchasing a new tank or at any time; the monthly clean out of the tank is an excellent time to do it. Your fish will enjoy a healthier environment and your aquarium, and entire room, will be transformed by this simple addition.

Secrets To Keeping A Great Looking Fluval Edge Aquarium

Posted on by admin

Fish lovers throughout the world have cheered with the advent of the new age Fluval edge aquarium. Fluval edge aquarium for sale is available within $139.99 in the US (6 gallon tank, size 22.4 cm x 26 cm x 46 cm). The elegant design with a stunning finish of a 3D water-cube gives an impression of your good taste. However, before buying one, one should be aware of all the small details about its maintenance, future considerations and many other handy topics that are bound to be implemented after the purchase.

So come take a tour of the top 10 secrets of the beautiful Fluval Edge Aquarium

Generally this tank is a recommended freshwater setup mainly for Fluval edge tropical fish. Even if it is converted into a marine setup, it would likely pose a great challenge for the owner

The light fixture consists of two 10 watts halogen bulbs with a hinged structure, which can be lifted out of the way while the customer does the maintenance on the aquarium, is the most advantageous. Also the top canopy contains many small holes which allow warm air, which is generated by the bulbs, to escape. This feature gives the tank a certain degree of robustness.

These aquariums come with hidden three stage power filtration technique that allows biological, mechanical and chemical cleaning resulting in cleaner water.

One of the drawbacks of this aquarium is that it does not come with a heater; while tropical fishes require an aquarium heater. So you may need to buy Fluval edge fish tank with shatterproof 25 Watt Edge heater.
The Fluval Edge fish tank is not compatible for any automatic feeder while the cover is in place. If the cover were to remain off, a battery powered feeder could be added.

The entire volume of the filter chamber is used to provide maximum filtration for the given space. The recirculation flow grid reduces the water flow by up to 60%. If it is too strong for the fish, one should place a foam protector in front of the input siphon area as an extra safety measure for smaller fish.

For the maintenance to be easier, a Fluval edge maintenance tools kit is recommended. This kit includes an Edge Gravel Vac, Edge Algae Magnet and an Edge Fish Net, which are specially designed to allow easier access through the top opening.

For more efficient cleaning, a foam block for the gross particles, the carbon insert that clears the water as crystal by removing chemicals and dyes are recommended. A biological filter may be added to stimulate beneficial bacteria.

For decoration a Fluval edge bamboo wall worth around $28.29 may be used.
Last but not the least, there should be a minimum of 3 litres of water for every 1 cm of fish, excluding the tail. 5-6 small species should be enough.

Tropical Freshwater Fish That Will Look Good In Your Aquarium – B To C

Posted on by admin

Brown Acara – Aequidens portalegrensis (Family: Cichlidae)
The main body color of the adult is reddish-brown, the scales are large and the fins are greenish and marbled with a range of colors. A horizontal line of dark colored bars runs from the eye to near the tail at which there is a dark area surrounded by yellow or green dots.

Although timid, it can grow to more than 15 cms so you need to consider if it is ideal or not for your community tank. The difference between the sexes is subtle. The anal fin of the male is longer and less rounder than that of the female and the colors of the fins are less bright. After mating the pair stay together for life which is a particular feature of the species.

The breeding tank must have rocks and similar stuff removed as the fish can be injured during the vigorous courtship. The pair should be about the same build and be fed on live food. Place a piece of slate in the tank so eggs can be laid on it and when the fry are hatched and able to swim remove both the parents. Feed the fry on infusoria, micro-worms and daphnids.

Cardinal Tetra – Cheirodon axelrodi (Family: Characidae)
One of the most popular tetras and great for a community aquarium as it is active and peaceful. Slim, it grows up to about 7 cms, ideally should be part of a small shoal and giving them live food now and again will keep them fit and healthy.

From the mouth and eye to the tail runs a reddish-brown coloration covering most of the lower body. Above that runs a green fluorescent band. The dorsal and anal fins have no color. The male is less thicker in the body than the female. This species is not easy to breed. Suitable pairs are picked by observation and kept apart feeding with live food to get them ready.

The female is placed in the breeding tank in the morning and the male in the evening. The tank will be thickly planted at one end with nylon breeding mops scattered about. The next day spawning should take place and semi-sticky eggs will be placed in the breeding mops which are then removed to a separate tank at the same temperature. After five days left in darkness you should find fry swimming about which can then be fed on infusoria till they are ready for bigger food such as micro-worms.

Chocolate Gourami – Sphaerichthys osphromenoides (Family: Belontiidae)
Although it can be put in a community tank this fish is quite susceptible to disease so be warned. But once it gets through any illness and gets used to the environment it is then quite hardy. Its aquarium requirements are soft water, a temperature of 26 to 30 degrees centigrade and a densely planted area.

The body color is from dark brown to black and it has several vertical silver white stripes of different shape. The mouth shows tiny teeth and the pelvic, dorsal and anal fins are black. As bubble-nest breeders the eggs are produced by the female after mating, the male puts them in his mouth and blows them into the bubble nest he previously built floating on the surface.

Remove the female after she lays the eggs. The male looks after the eggs; he will replace eggs that fall from the nest, he will maintain the nest structure with additional bubbles and aerate the eggs by swishing his tail near them. Remove the male after the fry start swimming.
