Ammonia Alert continuously monitors ammonia levels, and provides you with a quick and easy way of checking your water parameters. A sensor changes reversibly from yellow to green to blue, relative to ammonia levels. It can detect less than 0.05 ppm, and will alert you before any of your fish begin to show signs of stress.DirectionsSimply place inside the aquarium by the suction cup provided. It may take up to a few days for a new, dry sensor to calibrate with the water. Presence of 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.CareNo care is required beyond removing algae with a clean, soft material. Avoid touching the sensor with fingers, since skin oils can damage it. Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolour 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: colour should develop rapidly.SAFE:
