Choosing The Best Aquarium Filter For Your Fish

Caring for fish

Variety of aquarium filters

Many people are choosing to have aquariums with many different types of fish in them. Certainly, they are beautiful and relaxing to look at, but it takes some knowledge and work to ensure that your fish remain healthy and that your aquarium looks as good as you envision it will. One of the ways to ensure that it does is by choosing the best aquarium filter for your fish.

Even before deciding upon the filter, you need to decide what type of aquarium you will have. If this will be your first aquarium, it’s advisable that you start with a small aquarium first, as they are a little easier to maintain. Plus, you can always upgrade to a larger aquarium if the need and desire arise later.

Second, you need to carefully consider what filter will work best with your chosen aquarium. The filter is vital equipment, as it removes impurities from the water of your aquarium either via fine physical obstacles or via chemical processes. Choosing the right type of filter now can save you from hours of backbreaking maintenance work later on.

You should consider all three types of filters: biological, chemical, and mechanical.

Wet-dry filters actually employ all three types of filtration systems mentioned above, leading to less maintenance requirements than other types of filters. Wet-dry filters are more expensive, however, so they may not be the best choice for people who have an aquarium for the first time and/or are on a limited budget.

The three types of filters use different types of processes in order to eliminate the impurities in the water and to make the water cleaner and safer for your fish. Biological filters use bacteria to crack ammonia and nitrites.  Chemical filters use activated charcoal in order to eliminate unwanted dissolved wastes from the water. Mechanical filters use filtering particles and filter floss in order to remove impurities from the water.

If you choose to use a biological filter, it’s important to add the filter to the aquarium BEFORE you add the fish. You should also NOT add too many fish to the aquarium too soon, as the bacteria from the biological filter needs time to reduce the ammonia and nitrate levels. Too many fish in the water will cause the biological filter to work overtime, and the bacteria won’t be able to keep up with the increased demand, leading to high ammonia levels and the deaths of your fish.

You can help to make sure that there are enough bacteria in the water by using EcoBio-Block® products, which regularly adds nitrifying bacteria to new aquariums so that the water in your aquarium is safer and more beneficial for your fish. This will keep your water clear and healthy and reduce maintenance work.

One of the best choices of aquarium filters, especially for new and inexperienced aquarium owners, is an undergravel filter. This type of filter is inexpensive and totally keeps out debris from the aquarium. It also pulls water that is rich in oxygen through the gravel to help make the aquarium environment more livable for your fish.

One other type of filtration for you to consider is a sponge filter.  This filter is one that provides both mechanical and biological filtration. It has a large foam rubber (like a sponge) block that is connected to a lift tube or small power head. Water is drawn through the sponge to remove small particles from the water and to help grow bacteria that will keep your pond in great condition for your fish and plants.

Having your own aquarium tank can be a wonderful experience, as the beautiful fish can mesmerize you and your guests for hours. Maintaining the health of your aquarium does take some work, but by choosing the proper filter for your aquarium, you are well on your way to creating a hospitable and beneficial environment for your fish so that they can mesmerize you for hours on end.
