Seachem

Seachem One Year Combo Alert uses Seachem water sensor technology to continuously monitor ammonia and freshwater pH in your aquarium for an entire year, no tests or strips required. All you have to do is hang it in your tank!

• Continuous freshwater pH and ammonia readings
• No strips, no tests, just constant readings
• Easy monitoring - just hang in your tank

Ammonia Alert: The sensor automatically detects free ammonia at levels less than 0.05 mg/L (ppm) and alerts you to the presence of the primary killer of fish before it reaches hazardous levels and causes signs of stress. In the absence of free ammonia the sensor will assume a yellow color, and will move to green and blue as more ammonia is detected. Ammonia is detected continuously with a response time of just 15 minutes, allowing you to respond immediately and avoid further increases. Ammonia Alert lasts over 9 times as long as competing products, and is only about half the size.

pH Alert: pH is constantly monitored, with a sensor that alerts you to shifts in pH levels between 5.4 and 8.0 (freshwater only). It lasts up to 4 times as long as competing products and is small, clear, and unobtrusive when in the tank.

The Seachem Alert Combo pack is a revolutionary way to keep tabs on your aquariums essential levels. This unique tester provides continuous pH and ammonia readings for up to 6 months, eliminating the need for strips and complicated tests.

• Continuous freshwater pH and ammonia readings
• No strips, no tests, just constant readings
• Up to 6 months of constant monitoring

Alert Combo is easy to use: just place each reader somewhere visible in your aquarium, and you're done! After only a few minutes the readers will automatically detect and display your waters pH and ammonia levels using a simple color-coded system, and will continuously update every 10 minutes after that. No care is required beyond removing any algae accumulation with a clean, soft material.

Ammonia Alert works in freshwater and marine aquariums, and provides continuous readings for up to 1 year. pH Alert works only in freshwater aquariums, and provides continuous readings of pH levels between 5.4 and 8.0 for 3-6 months.

Seachem Ammonia Alert is an innovative color device for continuously detecting and monitoring free ammonia in aquariums. A sensor changes from yellow to green to blue, relative to the ammonia concentration in the water. Seachem Ammonia Alert detects less than 0.05 mg/L (ppm) free ammonia and alerts you before fish show any signs of stress. It lasts over a year and replacement sensors are available.

• Easy visual gauge to monitor ammonia in your reef or fish tank
• Use in saltwater or freshwater aquariums
• Provides 1 year of ammonia detection

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 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 register a SAFE reading.
