Choosing a Fish Tank Filter
September 16, 2013
The fish tank filter or filtration system is the single most important factor in maintaining a healthy environment and healthy fish. A recent article in Aquarium Fish Magazine estimates that more than 80 percent of all fish health problems in aquariums are directly linked to improper or inadequate filtration.
There are several types of filters used by today's hobbyists. An undergravel fish tank filter is the very least a tank needs to stay healthy.
THE UNDERGRAVEL FILTER:
An undergravel filter is a slotted plate situated inside the aquarium on the bottom glass under the aquarium gravel. Air bubbles or power heads are used to pull water down through the gravel and up through the lift tubes.
During this process, large particles are trapped in the gravel so that they are not suspended in the water - mechanical filtration. Additionally, nitrifying bacteria live on the surfaces of the individual gravel grains and "processes" the water as it goes by, converting ammonia to nitrite and nitrite to nitrate - biological filtration.
An undergravel filter plate should cover the entire bottom of the tank, and the gravel bed should be 2 to 3 inches thick. Gravel should have an average diameter of 3 millimeters (1/8 inch) to ensure lots of surface area for bacteria to grow on while providing enough space among the pieces to permit good water flow with minimal clogging. Water flow through the filter should be between 0.5 and 1.5 gallons per minute for each square foot of aquarium bottom area.
Should the undergravel filter bed become partially clogged with particulates, the water will channel around those areas and reduce nitrifying (biological cleansing) activity - the process of converting ammonia to nitrite to nitrate.
The result will be rising concentrations of ammonia. Meanwhile, without oxygenated water passing through some areas of the gravel, anaerobic regions (areas with minimal amounts of oxygen) will develop and become inhabited by undesirable bacteria (e.g., heterotrophic bacteria that produce deadly hydrogen sulfide gas, which smells like rotten eggs). If the gravel bed becomes totally clogged, the nitrifying bacteria (beneficial bacteria) will die and heterotrophic bacteria (undesirable bacteria) will take their place.
There are two ways to deal with this problem. One is to use a hydro-cleaning device, sometimes known as a gravel "vacuum." When siphoning water from the tank, the gravel is churned about in the large end of the siphon hose and the particulate matter is removed while the gravel remains in the tank.
The other method is to use efficient mechanical filtration to remove most of the solid material before it settles into the undergravel fish tank filter. Some people add a tank-mounted filter (below) as a supplemental mechanical filter to pull particulates from the water rather than have all of them drop to the bottom of the tank and begin to clog the gravel.
An undergravel filter is the least expensive and most common of all filters. It requires a filter plate and a pump or power-heads. Power heads usually give the undergravel filter a boost in that they move the water through the filter with the most speed and agitation.
TANK-MOUNT POWER FILTERS:
Tank mounted filters usually hang on the outside of the tank. They pull water out of the tank and let it trickle back into the tank. During the process, the water is passed through at least one and usually two filter pad inserts. The first traps any large debris that may be floating in the tank. The other allows nitrifying bacteria to grow on its surface so that biological filtration can also occur as the water trickles through.
The water pours back into the tank, dropping through a small amount of air space like a mini waterfall, which agitates the surface of the water and enhances the oxygenation of the tank.
It is very important to keep the mechanical filter pad clean. If it gets clogged, the water will bypass that pad and hit the biological filter pad full of particulates that will also soon clog the second insert. However, it is equally important that you not continually disturb the second or biological pad. Too fastidious a cleaning or using chlorinated water to wash the second pad can destroy the beneficial bacteria that are cleaning the tank.
Tank-mounted filters are a very good supplemental fish tank filter. They are not as expensive as most canister or wet/dry filters (below). Adding a tank-mounted filter to you existing tank will enhance the water quality because it will provide more filtration. More and better filtration will allow you to keep more fish in the same tank.
Another type of filter is the wet/dry filter.
THE CANISTER FILTER:
Canister Filters are one of the most popular and best types of fish tank filters. They provide all three types of filtration: mechanical, chemical, and biological filtration for larger tanks or tanks with lots of fish, but they take up less room than wet/dry filters (below). Some are so good at particulate filtering that they can actually be called a water polishing filters.
Depending on the model, they will contain one, two, or three media baskets. The idea is to push the water through the baskets, pulling pollutants out of the water as it passes through the media held in the basket. Canister filters take a little more work to set up (although they are getting more sophisticated every day), but their capacity and filtering ability are much better than power filters. Media needs to be changed or cleaned. Most have convenient snap-closures and some have quick disconnect hoses to make maintenance of the filter easy. Some are self-priming to make re-starting a breeze. They can be used for freshwater, saltwater, and cichlid tanks.
THE WET/DRY FILTER:
Wet Dry fish tank filters (also known as trickle filters) work on the same principle as undergravel filters, but implement the concept differently. The trickle filter's biological filtering bed is outside of the tank.
Aquarium water enters at the top of the filter column and trickles downward through the medium (e.g., stone, specially designed plastic media, fiber materials, etc.), which is not submerged, thereby collecting oxygen in the process. The nitrifying bacteria inhabit the surface of the medium and process (clean) the water as it trickles by. The water then collects at the bottom of the filter column and is pumped back to the tank.
This design provides for efficient nitrification, as well as good aeration (oxygenation) of the water. Some of the better commercial trickle filter designs incorporate drawers for mechanical filtering media and GAC (high quality granular activated carbon) so that the entire filtration system is built into one unit.
Trickle filters are particularly well suited for marine aquariums, where dissolved oxygen levels are low, and for freshwater aquariums that use a soil substrate for plantings, making undergravel filtration impossible. Unlike the undergravel filter, clogging is not a problem with trickle filters.
For best operation, the volume of the trickle column should equal about 8 to 10 percent of the tank volume. The water flow rate should be 4 to 5 times the tank volume per hour. For the most efficient nitrification, the filter surface area should be designed to yield 0.5 to 1.5 gallons per minute per square foot.
Both undergravel and trickle filters are sensitive to power failures. If the filter ceases to operate for more than 24 hours, halting the flow of water through the biological medium, the nitrifying bacteria will begin to die. Once water flow begins again, conditions will be similar to starting a biological filter in a new setup. In fact, conditions could be worse than a new system, as the dead and putrefying bacteria could poison the tank with a fast load of ammonia upon the re-start of the tank.
If only mechanical filtration is used, large particulates may be trapped in the mechanical filter medium, but there will be minimal biological filtration from the nitrifying bacteria in the mechanical filtering medium. Dissolved organic carbon such as fish waste and plant degradation will not be removed from the water and toxins can build up.
This limited amount of biological filtration will be very sensitive to changes in fish load (i.e., adding more fish or fish growth), changes in feeding rates, and even variations in water temperature. Nitrifying bacteria will have no surface to which to cling except in the mechanical filter medium. Moreover, scrupulous cleaning of the mechanical medium will wash away most of the nitrifying bacteria, leading to high ammonia levels in the water.
Adding a layer of Activated Carbon for chemical filtration of organic waste will not change the fact that there is no effective and reliable method for removing nitrogenous wastes. Carbon is used to remove impurities such as chlorine, not ammonia or its byproducts.
In a setup with only an undergravel filter, there is practically no chemical filtration for dissolved organ compounds. In addition, without an efficient mechanical filter, the nitrification bed will eventually clog with particulates. Nitrification will be reduced and life in the tank will decline.
In contrast, a filtering system comprised of all three components (mechanical, chemical and biological) provides all requirements for maintaining a healthy aquarium.
A typical wet dry filter does all three of these things. If cost is a consideration, an efficient setup consists of one outside power filter - either a hang-on-the-back unit or a canister - with separate compartments for mechanical media, GAC and ion exchange resin. It is important that the filter is large enough to accommodate the appropriate amount of filtering material.
An alternative setup uses two independent filter units. An outside power filter that contains mechanical media and activated carbon to remove particulates and dissolved organic compounds is run in conjunction with an undergravel filter.
Although a complete filtration system will cost a little more in the beginning, you save in the long run by avoiding the costs of replacement fish for those that died and medications for fish that become ill. More importantly, your fish will thrive and your aquarium will be more enjoyable. A properly filtered aquarium requires less maintenance than one with incomplete or inadequate filtration.
No filtration system, however, can keep aquarium water as clean and healthful as it was from the tap. Over time, the water quality deteriorates. Therefore, periodic water changes of 20 percent of the aquarium water are a necessary part of your total filtration system. A conscientious hobbyist can achieve the necessary good water quality with a minimal amount of effort and a good filtering design.

March 16, 2013
With all the different cat food brands being sold today, it is difficult to determine what is the best one for your cat. Certainly, it is important to find a product that your cat will love and one that is good for his health. In order to do that, you need to ensure that the cat food you purchase contains all the necessary ingredients that your feline needs. Read on to discover what is the best cat food for cats that will keep them healthy and allow them to live a long life.
Although Whiskas, Purina, and Friskies are popular cat food brands around the world, none of these are considered the best cat food in the market. In fact, among the different brands, these often end up at the bottom of the list. Time and time again, many cat owners consider Science Diet at the top of the list for their loved cats. Eukanuba, Evo Weight Management, and Innova also land top spots when it comes to the best dry and wet cat food.

Science Diet Mature Indoor is a dry version, which is considered the best cat food available. The wet food version is the Science Diet Adult Optimal Care. It’s considered the best for cats is because it promotes health in cats, ensuring that they receive a balanced diet for them to live a long, healthy life. In addition, the company itself has great environmental practices and policies. They make sure to give back to society through a shelter program for pets that they developed for the purpose of feeding homeless pets around the country.
If you want to ensure that your cat receives the best cat food and a healthy balanced diet, then you may want to consider the Science Diet brand. Feed your feline a mixture of wet and dry food so that he can receive nutrients offered in both types. Wet food consists of meat, while dry food is usually made of plants, so it would be ideal to give your cat a mixture of both.
Choosing the best cat food for your feline friend is important, as you want to make sure that he receives proper nutrition. With a healthy balanced diet, you will feel more at peace knowing that your cat will live longer. Always check to see the ingredients of the cat food you purchase to ensure that it contains all the vitamins and minerals your cat requires.

Feeding Your Puppy the Right Way With the Best Puppy Food
March 13, 2013
Feeding your puppy is certainly different from feeding an adult dog. Puppies grow twenty times faster than fully grown dogs, which is why they need a special diet that will help them with their physical development. Since puppies grow at a fast rate, their feeding regime changes every few weeks as well. Discover the right way to feed your puppy with the basic feeding guide below and make sure to get the best puppy food for your new little pet.
First Eight Weeks
During the first 8 weeks of their life, puppies should be kept with their mother. Most puppies that are separated from their mother before this period often have difficulty adjusting and end up being sickly. Being with their mother allows them to have their mother’s milk that provides antibodies and the right nutrients to make them healthy dogs.
-Three to Four Weeks
Puppies will need to start eating solid food when they reach 3 or 4 weeks. Mix the best puppy food with some water or milk to make it easier for your puppy to digest.
-Six to Eight Weeks
When puppies reach 6-8 weeks, they need to be fed 3 or 4 times a day. Make sure you choose the best puppy food that offers the right nutritional balance for the needs of your puppy. Check the label for meat, calcium, and protein, which are all important ingredients.
After Eight Weeks
After the first eight weeks, you can then start feeding your puppy two times a day all the way to his adult life.
Three to Six Months
At this age, your puppy will go through teething. This may make him a picky eater or he could even lose his appetite. It is important to continue feeding him the best puppy food filled with nutrients, twice a day. At any time you notice an upset stomach going on for more than two days, you need to bring your puppy to the vet.
Six Months to One Year
It may look like your puppy is all grown up but he is in fact still a puppy. You still need to feed him the best puppy food for proper nutrition.
After One Year
Most vets will allow you to switch to adult food once your dog has reached the one-year mark. It is best to consult with your vet about when to switch from the best puppy food to adult food to make sure your pet is getting the proper nutrients.
This is just a basic feeding guide for puppies. Keep in mind that each puppy may have different requirements. If you truly want to make sure that you are feeding your puppy the right way, it would be best to consult your veterinarian about your puppy’s specific needs.
Once your dog has a stable diet, you can start buying dog food in bulk. You might want to consider a healthy diet of homemade dog food.(1 Comment)
What Do Cats Eat?
March 9, 2013
When you think of cats and what they eat, the first thing that often comes to mind is an image of a cat drinking milk from a saucer. Some even think of cats eating kidney and fish. However, these are just the common perception of most people. Just because you think those things, it doesn't mean that you should actually feed your cat milk, kidney or fish.
So what do cats eat? Here you will know more about what cats really eat and what you should be feeding your feline.
What Do Cats Really Eat?
So, what do cats eat? In reality, cats are actually meat eaters. In fact, they need 2 or 3 times more protein than humans or dogs. Cats are built for metabolizing animal fats and protein. It is essential for cats to have complete amino acids in what they eat, which include Methionine, Cysteine, Arginine, and Taurine. This is because their bodies don’t make sufficient amounts of these nutrients so, it is important for them to consume it.
Cats don’t really use carbohydrates as much. Instead, for energy, they use the glucose that is released from protein. Of course, cats also need fat for good nutrition, and they need vitamin A, B, D, E, and K, along with minerals such as phosphorus and calcium.
What is the recommended diet for domesticated cats?
Typically, cat food is made up of carbohydrates, proteins, water, fats, minerals, and vitamins. When it comes to feeding domestic cats, you can choose between good quality wet or dry cat food. It really is a matter of what you prefer, or what your cat prefers.
Ideally, it would be best to give your cat a mixture of both. This is because canned food contains more meat, while dry food is produced mostly from plants. So, if you want your pet to have a healthy, balanced diet, then when it comes to figuring out what do cats eat, the answer is both wet and dry food. Having a balance of both would be the best for your feline.
I have a picky cat. What should I feed her?
But, what should you do if your cat is a picky eater? There are definitely cases where some cats would rather go hungry than eat what you feed them. The reason for this is that they are careful about what they eat, due to their sensitivity to some foods. So, if you discover that your cat is picky when it comes to food, make sure to stick to the cat food brands that he or she wants.
When you recognize this problem, try different brands until you find one that your cat likes. Figure out if your pet prefers dry food or cat food and stick it. In addition, always make sure his bowl is clean and there are no disturbances around that my affect how your cat eats.
You can feed your feline cat food so long as it contains all the nutrients necessary for healthy growth. Make sure to read the labels and find a good brand that your pet will love.
