The API Freshwater Master Test Kit is one of the brand's most recognised aquarium testing products.

It is designed to test key freshwater aquarium parameters including ammonia, nitrite, nitrate, pH and high-range pH.

Regular testing can help fishkeepers monitor the nitrogen cycle, identify developing water-quality issues and maintain more stable aquarium conditions.

API Water Conditioners

Tap water can contain chlorine, chloramines and other substances that should be treated before being added to an aquarium.

API water conditioners are designed to make tap water safer for aquarium fish and are useful when:

Setting up a new aquarium
Performing water changes
Topping up aquarium water
Transporting fish
Managing water-quality problems

Some API conditioners also provide additional support for ammonia, nitrite and nitrate depending on the product.

API Aquarium Treatments

API also produces a range of aquarium treatments designed to help manage common fish-health and water-quality concerns.

Always identify the problem carefully before treating an aquarium and follow the instructions supplied with the specific product.

Good filtration, stable water parameters and regular aquarium maintenance remain important alongside any treatment.

API pH & Water Chemistry Products

Different aquarium fish can prefer different water conditions.

API produces pH testing and adjustment products that can help fishkeepers monitor and manage aquarium water chemistry where necessary.

Before adjusting pH, it is important to understand the needs of your fish and the natural chemistry of your aquarium water.

Sudden changes should always be avoided.

Aquarium Water Testing for Healthy Fish

Many aquarium problems are difficult to see until fish begin showing signs of stress.

Regular testing can help identify changes in:

Ammonia
Nitrite
