Using advanced sensor technology, it changes color as conditions shift, offering a quick visual readout without the need for test kits or reagents. In normal conditions it may show a yellow or pale yellow-green hue; a greenish tint on a dry sensor is normal and can take a few days to equilibrate with water when first installed.\u003c\/p\u003e\n\u003ch3\u003eWhat makes it unique\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSeachem sensor technology for stable, long-term readings\u003c\/li\u003e\n\u003cli\u003eNo strips, no tests—constant readings you can trust\u003c\/li\u003e\n\u003cli\u003eSuitable for marine and freshwater tanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eKey specifications include detection of free ammonia down to 0.05 mg\/L, and a color progression from yellow to green to blue corresponding to concentration levels.

The unit lasts over a year under typical use. If the sensor is dry on installation, it may show a greenish hue and require a few days to equilibrate with the water. The absence of free ammonia is signaled by the yellow or faint yellow-green color, signaling normal conditions so you can proceed with confidence.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What does Seachem Ammonia Alert do?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It continuously monitors free ammonia with a color-change sensor, signaling safe or toxic ranges without water sampling.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How long does the unit last and how quickly does it respond?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Lasts over a year under typical use; responds to rising ammonia within about 15 minutes and reverts gradually after removal.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":53561544442185,"sku":"B000255R5G","price":21.36,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/1781\/9465\/files\/seachem-ammonia-alert-sensor.jpg?v=1766446762","url":"https:\/\/petvita.co.uk\/products\/seachem-ammonia-alert-continuous-free-ammonia-monitoring-for-freshwater-marine-aquariums","provider":"Petvita","version":"1.0","type":"link"}
