API pH Test Kit (250-test)

93 / 100A+4.6★ (3,350 reviews)

$7.98

A cheap, accurate liquid pH kit — the single most useful first test, covering the low range most tap water and community tanks sit in.

Pros

  • Liquid reagent gives granular readings a strip cannot, right across the low range
  • Hundreds of tests in one small bottle — an economical cost per test
  • Clear colour chart, numbered vials and good instructions
  • Matches lab results for freshwater pH in good light

Cons

  • Tests pH only — you still need ammonia, nitrite and nitrate kits
  • Low- and high-range are two separate bottles for the full pH picture
