{"product_id":"seachem-ammonia-alert","title":"Seachem Ammonia Alert","description":"Seachem Ammonia Alert is an innovative color device for continuously detecting and monitoring toxic free ammonia. 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. Marine or freshwater use.\n\u003cbr\u003e\u003cbr\u003e\nIn 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.\n\u003cbr\u003e\u003cbr\u003e\nAmmonia Alert lasts over 9 times as long as competing products (over a year compared to 4-6 weeks). Ammonia Alert is also almost half the size of competing products. It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.","brand":"VASCAAquariumSupply","offers":[{"title":"Default Title","offer_id":42621135355989,"sku":"RSC00100","price":4.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0646\/2626\/2101\/files\/SC00100-2.jpg?v=1781988320","url":"https:\/\/vascaaquariumsupply.com\/products\/seachem-ammonia-alert","provider":"VASCAAquariumSupply","version":"1.0","type":"link"}
