Ammonia Alert 1 year Seachem

It consists of a water-resistant color scale indicator and a replaceable sensitive film. This film, located in the center of the colored display, changes from yellow to green to blue depending on the level of ammonia present. Treated with care the sensor lasts over a year. A comfortable suction cup is included in the package.

Instructions

Place the indicator at a point well in view of the aquarium or filter. In the absence of ammonia free the central disc has a pale yellow or yellow-green color. The sensor placed in water may need a few days to balancing. No preliminary test type is required. The presence of ammonia in the free state is recorded after about 15 minutes from its appearance in the aquarium. The answer to a decline in the concentration of ammonia is slower. After the ammonia has been removed, about 4 hours are needed for the passage from toxic to a safe.
