Seachem Alert Combo Pack

Seachem Alerts Combo Pack, Now Ammonia Alert and pH Alert come together, Continuous freshwater pH and ammonia readings.

Ammonia Alert
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 and replacement sensors are available.
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.

pH Alert
Seachem pH Alert is a unique colour device designed to be placed in the aquarium to monitor pH continuously.
A sensor changes colour reversibly to alert you to shifts in pH levels between 5.8 and 8.6
*** Freshwater Only. Simply place pH Alert visibly anywhere in the aquarium or filter. It’s that easy.
No chemicals or test procedures are required.

When first put in service, response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes. The life of the pH Alert sensor may vary depending on a variety of tank parameters, typical sensor life is 3-6 months. Sensor exhaustion is indicated by a visible fading or washing out of sensor colour.

Avoid touching sensor surface with fingers.
