pH Alert

  • Seachem sensor technology
  • Continuously monitors pH in freshwater
  • No tests, no strips
  • Lasts up to 4 times as long as competing products

pH Alert is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. A sensor changes color reversibly to alert you shifts to in pH levels between 5.4 and 8.0. No tests, no strips, just constant readings. Freshwater Only.

pH Alert® lasts up to 4 times as long as competing products. pH Alert® is also almost half the size of competing products (1.5" x 2.5"). It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.

Ammonia Alert

Ammonia Alert is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. Marine or freshwater use.

In the absence of free ammonia the unit will assume a yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia.

Ammonia Alert® lasts over 9 times as long as competing products (over a year compared to 4-6 weeks). Ammonia Alert® is also almost half the size of competing products (1.5" x 2.5"). It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.

Kevin ★★★★★

After fumbling with messy test kits for years, these simple floating sensors are a game-changer for my freshwater tank. The continuous ammonia reading gives me real peace of mind, and they last way longer than the cheap strips I used before.

Lily U. ★★★★★

I've had these sensors in my tank for three weeks now, and the fact that they last up to four times longer than other brands is a huge plus. It gives me peace of mind without having to mess with test strips constantly.

Avery ★★★★★

The continuous readout is a game changer for my planted tank, no more mixing chemicals on the weekend. I just glance at the sensor card and know exactly where the pH is sitting. It’s been accurate for over two months now without needing a replacement.
