Seachem Laboratories 1 Year Ammonia Alert Monitor 1 Card, 1.5 In X 2.5 in

The Ammonia Alert® is a cutting - edge color - changing device designed to continuously detect and monitor toxic free ammonia. Its sensor reversibly shifts from yellow to green to blue, depending on the ammonia concentration. You don't need any test kits, chemicals, or complex procedures. This remarkable device can detect free ammonia at levels below 0.05 mg/L (ppm), alerting you to the top killer in your water before your aquatic friends show any signs of stress. It has a long lifespan of over a year. However, this product isn't suitable for use in acidic pH environments. Whether you have a marine or freshwater setup, it's a great addition.

Using the Ammonia Alert Monitor is a breeze. Just place the card in your water tank. You'll start seeing the sensor change color according to the ammonia level. Keep an eye on it regularly. As for the color, yellow means low ammonia, green indicates a moderate level, and blue shows high ammonia. A couple of things to note: don't use this product in acidic pH water as it won't work well. Also, don't let it dry out. To maintain it, make sure it's always submerged in the water. That way, it can keep working for over a year, keeping your tank a safe place for your aquatic pets.
