  • pH Alert is a unique colour device designed to be placed in the aquarium or filter and monitor pH continuously.
  • A sensor changes colour reversibly to alert you shifts to in pH levels between 5.8 and 8.2. No tests, no strips, just constant readings.
  • Freshwater Only.

  • Why Its Different

    pH Alert lasts up to 4 times as long as competing products. pH Alert is also almost half the size of competing products. It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.
