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.

Frequently Asked Questions

Can I use the Seachem Alerts Combo in a marine aquarium?
Ammonia Alert™ can be used in marine or freshwater aquariums. pH Alert™ is for freshwater aquariums only.

Does this combo require test kits or water samples?
No. Both devices are designed for continuous in-aquarium readings without sampling water, chemicals, strips or test procedures.

What ammonia level causes Ammonia Alert™ to change colour?
A greenish hue can appear at as little as 0.02 mg/L free ammonia. The ALERT colour is about 0.05 mg/L, ALARM about 0.2 mg/L, and TOXIC about 0.5 mg/L free ammonia.

How quickly will the ammonia monitor respond?
It detects the presence of free ammonia continuously, with a response time of about 15 minutes. A decrease in ammonia can take about 4 hours to move from TOXIC to SAFE.

What pH range does pH Alert™ monitor?
pH Alert™ monitors freshwater pH changes between 5.8 and 8.2. When first placed in service, it responds in about 30 minutes; thereafter, changes register within ten minutes.

How do I clean the alert sensors?
Gently remove algae with a clean, soft material. Do not use soap, bleach, detergents or hard objects, and avoid touching the sensor surface with your fingers.
