Depending on the pH value, an equilibrium exists in the water between ammonium ions (NH4+) and ammonia (NH3). At pH values ​​below 7, the largely harmless ammonium ions predominate, while at pH values ​​above 7, ammonia increasingly predominates. Ammonia is very dangerous because it impairs the respiration of living organisms. It easily penetrates cells, causing the pH value to rise and blocking vital functions. In a healthy, established aquarium, ammonium ions are quickly oxidized to nitrate via nitrite by nitrifying bacteria. If this process is disrupted, a sudden increase in the ammonium concentration can occur. Therefore, the ammonium\/ammonia concentration should be checked, especially in new aquariums.\u003cbr\u003e \u003cbr\u003eThis test measures the total ammonium\/ammonia concentration. For freshwater, a total ammonium\/ammonia concentration of 0.1 mg\/l is considered normal under typical conditions, with an upper limit of 0.5 mg\/l not to be exceeded. In seawater, the total ammonium\/ammonia concentration should be less than 0.05 mg\/l. However, the crucial factor is the pure ammonia concentration, which varies depending on the temperature and pH value and is derived from the total ammonium\/ammonia concentration.\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e Safety instructions: \u003cbr\u003e\n\u003ctable cellpadding=\"3\" cellspacing=\"0\" border=\"1\" width=\"100%\"\u003e\n\n\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\n\n\u003cdiv\u003e\n\n\u003cimg src=\"https:\/\/shop.aquaperfekt.de\/bilder\/pikto\/ghs_07.png\" width=\"60\"\u003e\u003cbr\u003e \u003cb\u003eDanger\u003c\/b\u003e \n\n\u003c\/div\u003e\n\n\u003cdiv\u003e\n\n\u003cimg src=\"https:\/\/shop.aquaperfekt.de\/bilder\/pikto\/ghs_05.png\" width=\"60\"\u003e\u003cbr\u003e \u003cb\u003eDanger\u003c\/b\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd title=\"\"\u003e H319\u003cbr\u003e H314\u003cbr\u003e\n\n\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e P102\u003cbr\u003e P305+P351+P338\u003cbr\u003e P301+P330+P331\u003cbr\u003e P303+P361+P353 \u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\n\n\n\u003c\/table\u003e\n\n\n\u003c\/div\u003e","brand":"Berghia Center","offers":[{"title":"Default Title","offer_id":56741855166839,"sku":null,"price":21.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/6500\/0567\/files\/G1674224833.jpg?v=1771186539","url":"https:\/\/berghiaglobal.com\/en\/products\/tropic-marin-ammonia-ammonium-test-seawater-freshwater","provider":"Berghia Global","version":"1.0","type":"link"}
