Seachem One Year Alerts Combo Pack pH and Ammonia

Description

Seachem Alerts Combo Pack pH and Ammonia (1 Year)

The One Year Alert Combo pack combines a year supply of Ammonia Alert (1 card) and pH Alert (1 card and 1 replacement sensor). Ammonia Alert and pH Alert are almost half the size of competing products. At 1.5" x 2.5", they are small, clear, and unobtrusive, so they won't detract from the view of your aquarium. Simply place Ammonia Alert and pH Alert visibly anywhere in the aquarium or filter. It’s that easy. No chemicals or test procedures are required.

Ammonia Alert's sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. It detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. 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. Marine or freshwater use.

pH Alert

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 from yellow to orange to red alerting you to shifts in pH levels between 5.4 and 8.0. When first put in service, pH Alert response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes. Freshwater use only.

Ammonia Alert: This device continuously monitors free ammonia (NH3), which is the toxic form of ammonia, in both freshwater and saltwater aquariums. It changes colour from yellow (safe) to green to blue (toxic) to indicate the ammonia concentration. The Ammonia Alert sensor is designed to last over a year.

pH Alert: This device continuously monitors freshwater pH levels. It changes colour from yellow to orange to red to indicate shifts in pH between 5.4 and 8.0 (though some sources state 5.8 to 8.2). The pH Alert sensor typically lasts 3-6 months, although some "One Year Combo" packs include a replacement sensor for the pH Alert to extend its usability to a year. Sensor exhaustion for the pH Alert is indicated by a visible fading or washing out of the sensor colour.

Key Features of the Combo Pack:

Continuous Monitoring: Unlike traditional test kits, these devices provide constant, real-time readings.
No Chemicals or Test Procedures: Simply place them visibly in your aquarium or filter.
Small and Unobtrusive: Their compact size means they won't detract from your aquarium's appearance.
Early Warning: They alert you to potential issues before they become critical for your aquatic life.
Lifespan: The Ammonia Alert lasts over a year, and the pH Alert (with or without a replacement sensor, depending on the specific combo pack) is designed to provide monitoring for a significant period.
Important Notes:

The Ammonia Alert specifically measures free ammonia, not total ammonia. Free ammonia is the harmful form.
The pH Alert is for freshwater use only.
The lifespan of the pH Alert can vary depending on tank parameters, and it may have a shorter lifespan in acidic water.
Both sensors improve in sensitivity with age, provided they are not allowed to dry out.
To check if the Ammonia Alert is still functioning, you can briefly hold it over the mouth of an ammonia bottle (like Windex); the sensor should rapidly change to a dark blue.
