·       Antichlorine : 

Purpose: Removes chlorine and chloramine from tap water, which can be harmful to fish.

Usage: Tap water is often treated with chlorine or chloramine to make it safe for human consumption, but these chemicals are toxic to fish and beneficial bacteria in aquariums. Antichlroine neutralizes these chemicals, making the water safe for aquatic life. This type of conditioner is essential during every water change or when you top up water into your fish tank.

Examples: Seachem Prime, Aquaforest AF Water Conditioner, Mydilab Tension Gon, YEE Antichlorine Tablets.

·       Nitrifying Bacteria

Purpose: Introduces beneficial bacteria that promotes tank cycle and breaks down harmful compounds like ammonia and nitrites.

Usage: Biological conditioners contain living bacteria that help break down ammonia and nitrite, which are toxic to fish. These are ideal for new tank setup during the cycling process, and can also be beneficial in existing tanks if the biological filter has been affected due to over-cleaning or medication use. By establishing a healthy colony of beneficial bacteria, biological conditioners support a stable, long-term filtration system, and mostly importantly, crystal clear water!

Examples: Seachem Stability, Aquaforest Life Essence, Supervital Nitrifying, YEE Nitrifier

·       Clarifier

Purpose: Clears cloudy or murky water by binding together small particles, such as debris, algae, dirt, and waste, that cause cloudiness in your fish tank.

Usage: In new tanks or when fine particles are present. After cleaning or stirring up substrate, causing temporary cloudiness, this water conditioner can be used to bind these dust or particles, which will sink later or filtered out by the aquarium filter wool.

Example: Seachem Clarity, ATAPet Water Clarifying Agent

·       Ammonia Neutralizers

Purpose: Detoxifies ammonia, a common and harmful compound in aquariums. 

Usage: Ammonia buildup can occur in new tanks, overstocked aquariums, or when there’s a filter failure. Ammonia neutralizers convert ammonia into a non-toxic form that is safe for fish and can be removed by the tank’s biological filtration over time. Ammonia-neutralizing conditioners are especially useful during the initial cycling process of new tanks or during the first time of entering live stocks to prevent ammonia spike.

Examples: Seachem AmGuard

Water conditioners play an important role in creating and maintaining a safe, healthy aquarium environment. With a wide variety of options, from dechlorinators to biological conditioners, understanding the purpose of each type allows aquarists to make decision that meet their aquarium’s requirements.

For a successful aquarium keeping, be sure to use a conditioner that matches your tank’s specific needs and helps establish a balanced ecosystem for all its inhabitants.
