API TAP Aquarium Water Conditioner 32 oz — Concentrated Chlorine & Heavy Metal Neutralizer, Instant Action

API TAP Aquarium Water Conditioner is a concentrated treatment that instantly neutralizes chlorine and chloramines and detoxifies heavy metals so tap water is safe for fish in freshwater and saltwater tanks.

Tap water contains disinfectants and trace metals that are safe for people but harmful to aquatic life; treating water before introducing it to an aquarium prevents gill irritation and stress. API TAP is a long-standing, research-backed formula that treats up to 10 gallons with just 3 ml, making it both economical and simple to use during tank setup, routine water changes, or when adding new fish.

How quickly does API TAP make tap water safe for fish?

API TAP acts immediately on common tap disinfectants, so treated water is ready for fish as soon as you add the measured dose and gently mix it into the aquarium. No long waiting period is required, which is helpful when performing fast water changes or adding new livestock.

• Instant neutralization of chlorine and chloramines on contact
• Works immediately to detoxify trace heavy metals
• Suitable for use right before or during water changes

Will this product work in both freshwater and saltwater aquariums?

Yes — the formula is safe for all aquatic environments, including freshwater, saltwater, and reef systems when used as directed. It’s formulated to protect fish and other inhabitants from common tap water contaminants without altering salinity when used at recommended rates.

• Safe for tropical community fish, cichlids, goldfish, and marine species
• Compatible during aquarium setup, routine maintenance, and fish additions
• Does not affect aquarium salt levels when applied correctly

How concentrated is the bottle and what is the dosing?

The 32-ounce concentrate is highly potent: a small volume treats a large amount of water, so a single bottle will last through many water changes. Typical dosing is up to 3 ml per 10 gallons, but follow package directions for precise volume and special situations.

• Up to 3 ml treats 10 gallons of tap water
• Concentrated formula reduces frequency of repurchase
• Measure carefully to maintain optimal water chemistry
