API Nitrite Test Kit (180-test)
$11.83
A dedicated liquid nitrite kit for cycling a new tank — reads the low range that matters when nitrite is spiking and fish are at risk.
Pros
- Liquid reagent gives granular readings at the low nitrite range a strip pad cannot resolve
- Hundreds of tests per bottle — an economical cost per test while you cycle
- Numbered vials, a clear colour chart and good instructions
- Pairs with a master kit to confirm the ammonia nitrite nitrate cycle has finished
Cons
- Single parameter — only really useful during cycling or a suspected spike
- The colour step between safe and toxic is subtle at the very bottom

$36.26 · 89 / 100A
The accuracy reference for freshwater: a liquid reagent kit that reads far more granular than strips and covers the full ammonia nitrite nitrate cycle plus high- and low-range pH.
$24.98 · 85 / 100A−
The fast everyday check — five parameters in about a minute. Less granular than liquid, but the most-reviewed strips in the hobby.
$14.97 · 87 / 100A
The cheapest way to eyeball six parameters — a fine budget strip for routine checks, not for diagnosing a crisis.
