A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg\/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year and replacement sensors are available. Marine or freshwater use.\u003c\/p\u003e\n\u003cp\u003eIn 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.\u003c\/p\u003e\n\u003cp\u003epH Alert:\u003cbr\u003epH Alert is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously.\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"text\"\u003e\u003cspan\u003eA sensor changes color reversibly to alert you shifts to in pH levels between 5.8 and 8.6.
