API TAP WATER CONDITIONER – 1-Gallon Aquarium Water Conditioner

Smart water care for every aquarium

Healthy fish start with clean, balanced water. API TAP WATER CONDITIONER helps prepare tap water for safe introduction to your tank. Its approach is practical and fast, designed for busy hobbyists who want reliable results without fuss.

What it does

Chlorine and chloramines—common in tap water—can irritate fish and hinder oxygen uptake. This conditioner instantly removes chlorine and neutralizes chloramines, helping make water more fish-friendly from the moment you treat it. It also detoxifies heavy metals that may be present, easing potential stress on newcomers and routine maintenance alike.

Concentrated formula for small, precise doses

The product line is described as super-strength and highly concentrated, so you only need a small dose to treat larger volumes. In practice, up to 3 mL can treat 10 gallons. This efficient dosing supports careful water prep during setup or after water changes.

• Use during aquarium setup to create a stable starting environment
• Apply during water changes to maintain consistent water quality
• Add when introducing new fish to help minimize stress from tap water residue

• Compatible with freshwater and saltwater tanks
• Pairs well with other API care products for a complete routine

Versatile for freshwater and saltwater

Designed for both freshwater and saltwater systems, API TAP WATER CONDITIONER is compatible with a wide range of aquariums—from community tanks to specialized setups. While it is not a cure-all, it can be part of a routine that aims to support a hospitable habitat for tropical fish, cichlids, goldfish, and more.

How to make the most of it

Pair this conditioner with the rest of API’s care lineup for a streamlined routine. Always follow dosing directions and add the treated water before introducing fish or other inhabitants. Regular use during routine maintenance may contribute to steadier water conditions over time.

Reliability you can rely on

API has a long history of developing fish care products based on research and practical testing. This conditioner is designed to work in harmony with other API products, supporting a broader approach to water quality and fish welfare in mixed-volume tanks and reef-friendly environments.
