The color changing sensor of Seachem's
Ammonia Alert lets you know when free ammonia levels are dangerously high! Four
levels of ammonia detection, safe, alert, alarm, and toxic, keeps you aware of
your tank's current ammonia content. Will accurately read ammonia levels even if
an ammonia remover is in use.
Remove protective film. Place the unit visibly anywhere in the aquarium or
filter. In the absence of free ammonia the unit will assume a yellow or faint
yellow-green color. It may take up to a few days for a dry sensor to equilibrate
with the water. The presence of free ammonia is detectable continuously with a
response time of about 15 minutes. Response to decreasing ammonia is slower,
requiring about four hours to go from "toxic" to "safe" upon removal of ammonia.
Remove algae growth from the sensor with a clean, soft material. Do not use
bleach, soap, detergents or hard objects to clean the sensor. Avoid touching the
sensor with fingers, since skin oils can damage it. Dye medications may discolor
