Maintaining nitrate concentrations slightly higher than natural reef levels has been observed by many aquarists to be beneficial to coral health and coloration. This may be because higher nitrate levels compensate for the lack of planktonic food organisms and particulate organic nitrogen available to corals in the wild.\u003c\/p\u003e\n\n\u003ch2\u003eRaising nitrate without importing phosphate\u003c\/h2\u003e\n\u003cp\u003eWhen phosphate levels are already high, increasing food input becomes problematic when trying to raise nitrate — because food also imports phosphate. \u003cstrong\u003eB-Ionic Nitrate solves this by raising nitrate without increasing phosphate.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBiological assimilation and denitrification convert the added nitrate into carbonate alkalinity, so there is \u003cstrong\u003eno accumulation of sodium or potassium\u003c\/strong\u003e, two elements that are difficult to test for.

Nitrate is a necessary nutrient: at zero, corals brown out, pale, or stop growing. Maintaining a measurable level supports health and coloration.\u003c\/p\u003e\n\u003ch3\u003eWhy not simply feed more?\u003c\/h3\u003e\n\u003cp\u003eBecause food also brings phosphate. If your phosphate is already high, increasing feeding makes the problem worse. B-Ionic Nitrate raises nitrate on its own, without touching phosphate.\u003c\/p\u003e\n\u003ch3\u003eDoes it unbalance the water like other nitrate supplements?\u003c\/h3\u003e\n\u003cp\u003eNo. The nitrate is supplied as purified calcium nitrate: biological denitrification converts it into carbonate alkalinity, leaving behind no accumulated sodium or potassium, unlike other formulations.\u003c\/p\u003e","brand":"ESV","offers":[{"title":"32 oz","offer_id":38011277934763,"sku":"ESV221","price":29.99,"currency_code":"CAD","in_stock":true},{"title":"16 oz","offer_id":47561110290603,"sku":"ESV220","price":19.99,"currency_code":"CAD","in_stock":true},{"title":"1 gal","offer_id":47561110323371,"sku":"898636002600","price":79.99,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0513\/7108\/1899\/files\/s221404288438777473_p125_i1_w600.jpg?v=1707778002","url":"https:\/\/reefsolution.com\/en\/products\/esv-b-ionic-nitrate","provider":"Reef Solution","version":"1.0","type":"link"}
