SEACHEM Ammonia pH Alert Stick-On-Tank Ammonia Reading

Seachem Ammonia Alert

Seachem Ammonia Alert continually monitors and detects the level of free ammonia in your aquarium and visually alerts you by colour changes on its sensor. Free ammonia is much more toxic than ionized ammonia, and needs to be removed to avoid harm to aquarium systems. This Ammonia Alert ammonia monitoring kit is sensitive, and as little as 0.02 mg/L of free ammonia which 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. 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.
This product is suitable for marine or freshwater use. This product is not recommended for use at acid pH.

Benefits
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.
Ammonia Alert lasts over 9X as long as competing products.
Ammonia Alert is also almost half the size of competing products. It is small, clear, and unobtrusive, so it will not detract from the view of your aquarium.
Provides visual alerts through colour changes

Seachem pH Alert (6 Month) (SC-20)

Seachem pH Alert is a small unobtrusive sensor with a size that is almost half and lasts up to 4 times as long as competing products. It monitors the water 24 x 7 and changes colours according to the pH level. Seachem pH Alert continually monitors the pH level of freshwater aquarium and visually alerts you by colour changes on its sensor.
Simply place the Seachem pH Alert in the aquarium or filter and it will monitor pH continuously. Its sensor changes color

Directions
Simply place Seachem pH Alert visibly anywhere in the aquarium or filter and match the sensor color to the corresponding pH reading on the color wheel. Its 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.
