Permanent Test for Measuring Ammonia and pH Levels in Water, Seachem Alert Combo Ph-Ammonia (1 Year)

Description

The One Year Alert Combo package combines a one-year supply of Ammonia Alert (1 card) and pH Alert (1 card and 1 replacement sensor). Ammonia Alert and pH Alert are nearly half the size of competing products. At dimensions of 1.5" x 2.5", they are small, clear, and discreet, ensuring they won't obstruct the view of your aquarium. Simply place Ammonia Alert and pH Alert visibly anywhere in the aquarium or in the filter. It's that simple. No chemicals or testing procedures are required. **Ammonia Alert** The Ammonia Alert sensor changes reversibly from yellow to green to blue, depending on ammonia concentration. It detects less than 0.05 mg/L (ppm) of free ammonia and alerts you to the number one killer before any signs of stress appear. The presence of free ammonia is continuously detectable, with a response time of approximately 15 minutes. The response to decreasing ammonia is slower, taking about 4 hours to transition from TOXIC to SAFE once ammonia is eliminated. Suitable for marine or freshwater environments.

**pH Alert** pH Alert is a unique colored device designed to be placed in the aquarium or in the filter to continuously monitor pH levels. A sensor reversibly changes color from yellow to orange and to red, alerting you to changes in pH level between 5.4 and 8.0. Upon initial setup, the response time for pH Alert will be approximately 30 minutes. Subsequently, pH changes will be recorded in ten minutes. For freshwater use only.
