The Seachem Alerts Combo Pack provides a convenient and continuous way to monitor two critical water parameters in your aquarium: ammonia and pH. This pack includes both the Ammonia Alert and pH Alert, offering a full year of passive monitoring without the need for traditional liquid test kits or complex procedures. Simply place these compact devices directly into your tank or filter, and they will visually indicate parameter shifts, allowing for proactive adjustments to maintain a healthy environment.

Each alert device measures just 1.5" x 2.5", ensuring they remain unobtrusive in your display tank. The Ammonia Alert features a sensor that changes reversibly from yellow to green to blue, detecting free ammonia concentrations as low as 0.05 mg/L (ppm) and providing continuous alerts within 15 minutes of an increase. This crucial device is suitable for both marine and freshwater aquariums. The pH Alert, designed for freshwater use only, monitors pH levels between 5.4 and 8.0, with its sensor shifting colors from yellow to orange to red. It registers pH changes within ten minutes after an initial 30-minute activation.

This combo pack is ideal for both novice and experienced aquarists seeking a hassle-free method to safeguard their aquatic inhabitants. By offering continuous, at-a-glance monitoring, it eliminates the guesswork and frequent manual testing often associated with maintaining stable water chemistry. The early detection capabilities of both alerts help prevent stress and potential loss of fish and invertebrates, making it an essential tool for maintaining optimal water quality and a thriving aquarium ecosystem.
