Seachem Alerts

Seachem Ammonia Alert is used for continuously detecting and monitoring toxic free ammonia levels in both marine and freshwater aquariums without the need for tests or chemicals.

  • Seachem sensor technology
  • Continuously monitors ammonia and freshwater pH
  • No tests, no strips
Ammonia Alert™ is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. Marine or freshwater use.

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, chemicals, 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 go from TOXIC to SAFE on removal of ammonia.

Why Its Different

Ammonia Alert™ lasts over 9 times as long as competing products (over a year compared to 4-6 weeks). Ammonia Alert™ is also almost half the size of competing products. It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.

Interpretation

As little as 0.02 mg/L of free ammonia will produce a greenish hue on the detector surface. This corresponds to a total ammonia (both ionized and free ammonia) of 0.25 mg/L in marine water at pH 8.3. In freshwater at pH 7.0, this corresponds to 3.6 mg/L total ammonia. Free ammonia is much more toxic than ionized ammonia. As free ammonia, the ALERT color corresponds to about 0.05 mg/L, ALARM to about 0.2 mg/L, and TOXIC to about 0.5 mg/L. The ALERT concentration is tolerated for several days, ALARM for a few days, and TOXIC is rapidly harmful. This product is not recommended for use at acid pH

Care

No care is required beyond removing algae with a clean, soft material. Avoid touching the sensor with your fingers, since skin oils can damage it. Do not use bleach, soap, detergents, or hard objects to clean the sensor. Some dye medications may discolor the sensor. Sensitivity improves with age, provided the unit is not allowed to dry out, however, drying does not permanently impair the unit. For maximum sensitivity, the unit should be read under natural daylight or daylight-simulating light. Red-enhancing light minimizes green and blue hues, decreasing the apparent sensitivity of the unit. The response of the unit may be checked by holding it briefly over the mouth of an ammonia bottle: color should develop rapidly.

I even used it on my face
Color: Bronze Gold
I purchased this shimmer oil to use on my legs when I’m wearing a summer slip dress. I’m not always fond of how my legs look, but once I smoothed this over my lightly tanned skin—wow, what a difference. The glow is subtle yet so flattering. One day I forgot my highlighter, so I lightly dabbed this over my contour, brushed a tiny bit over my lips with chapstick on top, and it looked amazing. Now it’s my go-to beach look: a little shimmer on my arms and legs, a tad on my lips, a soft sweep across my eyelids, and a touch on my cheekbones. It gives me that effortless, radiant vibe that’s perfect for summer.

Smells like crayons
Color: Bronze Gold
Stinks. Smells like covering yourself in melted crayons. Very cheap smelling. Left it on ny skin for an hour, then wiped with a rag and it immediately came right off. You're better off just getting bronzer.
