Fritz Complete (16 oz)

92 / 100A+4.8★ (1,550 reviews)

$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

Alternatives

Seachem Prime (500 mL)

$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.

API Tap Water Conditioner (16 oz)

$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.

Seachem Safe (250 g)

$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.
