Product Information

API Aqua Essential 118 ml – Highly concentrated all-in-one aquarium water conditioner that instantly removes chlorine, chloramine and detoxifies heavy metals while temporarily detoxifying toxic ammonia, nitrite and nitrate. Suitable for freshwater, planted and marine aquariums. Ideal for new tank setup, water changes, fish transport and emergency water quality management. Made in the USA.

The Complete Water Conditioner for Freshwater, Planted & Marine Aquariums

Every water change introduces chlorine, chloramine and sometimes heavy metals that can stress fish and damage beneficial bacteria. At the same time, fish continuously produce ammonia through respiration and waste, while uneaten food and organic debris contribute to ammonia, nitrite and nitrate accumulation.

API Aqua Essential is an advanced, highly concentrated water conditioner that performs multiple functions in a single dose. It:

• Instantly removes chlorine
• Neutralizes chloramine
• Detoxifies heavy metals
• Temporarily detoxifies ammonia, nitrite and nitrate
• Makes tap water immediately safer for fish
• Supports biological filtration by rendering toxic nitrogen compounds less harmful while the biofilter processes them

Unlike a basic dechlorinator, API Aqua Essential is designed for both routine maintenance and emergency water-quality support. It is suitable for freshwater, planted and marine aquariums.

Expert Recommendation from Something Fishy

API Aqua Essential is an excellent choice for hobbyists who want one conditioner that covers routine water changes and emergency water-quality management.

However, if ammonia or nitrite remains detectable, treat the underlying cause. Aqua Essential temporarily detoxifies these compounds—it does not replace biological filtration or regular maintenance. Always investigate why ammonia or nitrite is present and monitor the aquarium using a quality test kit.
