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.

SeaChem Ammonia Alert

Seems to do the job. It is staying on the "negative" color and is very easy/obvious to tell. There's not much else to say other than it provides me with a little peace of mind (as long as it works!) and I do not mind having it in my tank. It is a little bit of an eye sore, if that matters to you, so I stuck mine to the back corner where I can clearly see it but it's still kind of hidden. It only has the one small suction cup so it can pop off or flop around a bit in strong flow.
