API Tap Water Conditioner (16 oz)
$8.48
The cheapest effective dechlorinator: 1 mL treats 20 gallons. It removes chlorine, neutralises chloramine and binds heavy metals — but it does not detoxify ammonia, so keep a test kit handy while cycling.
Pros
- Removes chlorine and neutralises chloramine, works instantly, and binds heavy metals
- Highly concentrated — 1 mL treats 20 gallons, the lowest cost per gallon of any liquid here
- A 16 oz bottle lasts months of weekly water changes
- Does not affect pH and is gentle on biofilter
Cons
- No ammonia binding — chlorine, chloramine and metals only, so it will not detox an ammonia spike
- Thin, watery formula is easy to over-pour from the large bottle

Alternatives
$16.62 · 94 / 100A+
The benchmark conditioner: highly concentrated, full spectrum and overdose safe. One capful treats 50 gallons — it removes chlorine, neutralises chloramine and detoxifies ammonia and nitrite in a single dose.
$18.47 · 93 / 100A+
Powdered Prime for big tanks and fish rooms — the same full-spectrum chemistry in dry form, at the lowest cost per gallon in the hobby. Fiddly to dose in a small tank, unbeatable value in a large one.
$10.98 · 93 / 100A+
The dechlorinator that also heals: removes chlorine and neutralises chloramine while adding an aloe-vera slime coat that reduces stress and helps torn fins recover. Not an ammonia detoxifier.
