Fritz Complete (16 oz)
$19.99
A full-spectrum challenger to Prime: removes chlorine, neutralises chloramine, detoxifies ammonia and nitrite and even nitrate, and adds a slime coat. Excellent, if less famous and pricier per ounce.
Pros
- Full spectrum — removes chlorine, neutralises chloramine and detoxifies ammonia, and works instantly
- Also gives nitrite protection, detoxifies nitrate, and adds a slime coat
- Concentrated at 5 mL per 10 gallons and does not affect pH
- Shrimp safe and plant safe, and gentle on biofilter
Cons
- Pricier per ounce than Prime and less concentrated, so not the cost-per-gallon leader
- A smaller, newer brand with far fewer reviews than the API and Seachem staples

$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.

$8.48 · 94 / 100A+
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.
