Quick Answer: What Is Biological Filter?

Biological filtration refers to the process by which beneficial bacteria break down ammonia and nitrite and transform them into compound nitrate, which is much less toxic. Chemical filtration is a process by which chemical additives remove dissolved wastes from the water.

What is biological filter media?

Biological filter media (BFM) is a part of your tank filtration system made to help good bacteria grow safely. These bacteria are a very important part of your filter. But to help them keep your aquarium healthy, you need the best BFM you can get.

What does a biological filter remove?

Biological filters enable bacterial colonies to propagate and break down wastes. Biological filtration is the action of bacteria in the tank breaking down dangerous ammonia, converting them to nitrites, and then the nitrites to the less toxic nitrates.

How does a bio filter work?

Biofilters work by absorbing noxious gases into a biofilm where microorganisms break down the gases into carbon dioxide, water and salts and use the energy and nutrients to grow and reproduce.

What are the 3 types of filtration?

The Aquarium uses three main types of filtration: mechanical, chemical, and biological. Mechanical filtration is the removal or straining of solid particles from the water.

Is lava rock good bio media?

Lava rock – the igneous rock that forms as an erupting volcano’s molten lava cools and hardens – is very porous. When chunks of it live in your filtration system, you provide a lot of surface area for beneficial bacteria to colonize and grow. That’s what makes it such a great filter media.

What kills beneficial bacteria in aquarium?

Unfortunately, chlorine and chloramine will not only harm aquarium fish but can affect the entire aquarium system. These chemicals also kill beneficial bacteria and impair biological filtration.

How can I keep my aquarium water clear?

Keeping the aquarium very clean by removing debris such as decaying plants and uneaten food, vacuuming the gravel regularly, and performing partial water changes will quickly resolve most cases of bacterial bloom. Cut back feeding to every second or third day, which will reduce excess food decay.

Do you need bio media?

Registered. You don’t “need” any one specific media. Bio media, ceramic media, and sponge/foam media seem to do better for beneficial bacteria colony formation though than filter floss (which can clog up or break down more rapidly) or carbon bags/inserts.

Is biological filtration necessary?

Why You Need Biological Filtration One of the main uses for biological filtration is to convert harmful ammonia, which is toxic to fish and bad for a pond ecosystem, into nitrates. Another way is through scheduled partial water changes, which replace a portion of the pond water with new nitrate- free water.

How long does it take for a biological filter to work?

If new biofilters are used, it will take a number of weeks before bacteria have sufficiently increased in number to do their work properly. Fortunately you can add bacteria to the filter material yourself.

How do you grow nitrifying bacteria?

The water temperature for optimum growth of Nitrifying bacteria is approximately 75 – 85°F. Growth rate is cut to 50% at approximately 65°F, and cut by 75% at approximately 50°F. Growth is zero at approximately 40°F or below. Nitrifying bacteria will die if frozen, or if water temperature reaches 120°F.

How do I add bacteria to my aquarium?

Add Filter Media One of the most effective ways to make sure beneficial bacteria exist in your fish tank is by adding filter media. This will speed up the nitrogen cycle, which will also help remove ammonia from the fish tank since beneficial bacteria feed on ammonia and turn it into harmless compounds in your tank.
