Seachem pH Alert

The Seachem pH Alert is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. A sensor changes color reversibly to alert you shifts to in pH levels between 5.8 and 8.6. The Seachem pH alert is for freshwater use only.

DIRECTIONS:
Simply place the Seachem pH Alert visibly anywhere within the aquarium or sump filter. It’s that easy. No chemicals or test procedures are required. When first put in service, response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes. The life of the Seachem pH Alert sensor may vary depending on a variety of tank parameters. A replacement sensor is included to ensure effectiveness for 3 to 6 months. Sensor exhaustion is indicated by a visible fading or washing out of sensor colour.

Seachem Ammonia Alert

Seachem 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 Seachem 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 and replacement sensors are available. Seachem ammonia Alert is for 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.

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 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.
