Seachem Alerts Combo
Seachem Alerts Combo is a continuous in-aquarium monitoring set for aquarists who want to keep track of free ammonia and pH without water sampling, test strips or chemical test procedures. It combines Seachem Ammonia Alert™ for freshwater and marine aquariums with pH Alert™ for freshwater aquariums.
Key Benefits
- Provides continuous visual monitoring through reversible colour-changing sensors.
- Ammonia Alert™ detects free ammonia at levels below 0.05 mg/L (ppm).
- Its sensor changes from yellow to green to blue in relation to free ammonia concentration.
- pH Alert™ monitors freshwater pH shifts between 5.8 and 8.2.
- Small, clear devices are designed to remain unobtrusive in the aquarium.
- Ammonia Alert™ lasts over a year; pH Alert™ provides long-term in-tank pH monitoring.
How to Use
Place pH Alert™ visibly anywhere in the freshwater aquarium or filter. Position Ammonia Alert™ in the aquarium where it can be viewed easily. No water samples, chemicals or test procedures are required. A dry Ammonia Alert™ sensor may appear greenish and can take up to a few days to equilibrate in water.
Specifications
- Ammonia Alert™ response to free ammonia: about 15 minutes.
- Response when ammonia decreases: about 4 hours to move from TOXIC to SAFE after ammonia removal.
- pH Alert™ initial response time: about 30 minutes; later pH shifts register within ten minutes.
- Ammonia Alert™ colour levels: ALERT at about 0.05 mg/L free ammonia, ALARM at about 0.2 mg/L, and TOXIC at about 0.5 mg/L.
Suitable For
Ammonia Alert™ is suitable for freshwater or marine aquariums. pH Alert™ is for freshwater aquariums only. The Ammonia Alert™ device is not recommended for use at acid pH.
Care
Remove algae using a clean, soft material. Avoid touching the sensor with fingers, as skin oils can damage it. Do not use bleach, soap, detergents or hard objects. Some dye medications may discolour the sensor. For maximum sensitivity, read the device under natural daylight or daylight-simulating light.
What's Included
- Seachem Ammonia Alert™ continuous free-ammonia monitor.
- Seachem pH Alert™ continuous freshwater pH monitor.
