Unlike ammonia and nitrite, nitrate is far less toxic to fish, but prolonged exposure to high nitrate levels can cause stress, poor health, algae growth, and reduced vitality in fish and corals. Nitrate is invisible to the naked eye, so regular testing is important to maintain good water quality.\u003c\/p\u003e\n\u003cp data-end=\"945\" data-start=\"592\"\u003e\u003cstrong\u003eWhat is the recommended nitrate level?\u003c\/strong\u003e\u003cbr data-end=\"633\" data-start=\"630\"\u003eFor freshwater aquariums, nitrate should ideally be kept below 40 mg\/L (ppm). Sensitive fish species may require even lower levels. In marine and reef aquariums, nitrate levels are generally recommended to remain below 10–20 mg\/L (ppm), with reef systems often targeting very low nitrate levels for coral health.\u003c\/p\u003e\n\u003cp data-end=\"1375\" data-start=\"947\"\u003e\u003cstrong\u003eWhat do I do if the nitrate level is wrong?\u003c\/strong\u003e\u003cbr data-end=\"993\" data-start=\"990\"\u003eIf nitrate levels become too high, perform a partial water change to dilute the nitrate concentration. Regular maintenance such as gravel cleaning, avoiding overfeeding, improving filtration, and increasing live plant growth can also help reduce nitrate levels. In marine aquariums, protein skimmers, refugiums, or nitrate-removal media may assist in maintaining low nitrate levels.\u003c\/p\u003e\n\u003cp data-end=\"1388\" data-start=\"1377\"\u003e\u003cstrong\u003eHow to use?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"1942\" data-start=\"1390\"\u003e- Ensure the test tube is clean.\u003cbr data-end=\"1423\" data-start=\"1420\"\u003e- Take a 5 ml sample of water into the test tube.\u003cbr data-end=\"1473\" data-start=\"1470\"\u003e- Add the recommended number of drops of Nitrate Reagent 1 and shake thoroughly.\u003cbr data-end=\"1554\" data-start=\"1551\"\u003e- Add the recommended number of drops of Nitrate Reagent 2 and shake again thoroughly.\u003cbr data-is-only-node=\"\" data-end=\"1641\" data-start=\"1638\"\u003e- Wait the instructed development time, then compare the colour of the sample to the colour scale provided.\u003cbr data-end=\"1749\" data-start=\"1746\"\u003e- A pale or colourless sample indicates low nitrate levels, while deeper colours indicate higher nitrate concentrations.\u003cbr data-end=\"1870\" data-start=\"1867\"\u003e- Any colour forming after the recommended waiting time should be ignored.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"NT Labs","offers":[{"title":"Default Title","offer_id":48812456870145,"sku":"NT003","price":13.0,"currency_code":"SGD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0430\/9870\/1992\/files\/NTLABSTestNitrateNO3_1.png?v=1779098177","url":"https:\/\/eastoceansg.com\/products\/nt-labs-test-nitrate-no3","provider":"East Ocean Aquatic","version":"1.0","type":"link"}
