{"product_id":"reef-buffer","title":"Reef Buffer","description":"\u003cp\u003eWhen used as directed Reef Buffer™ will raise the pH of your reef system to 8.3 without fear of accidentally overshooting the pH to a dangerous level. Whereas competing products simply use sodium bicarbonate, Reef Buffer™ is made with a blend of carbonate and bicarbonate salts. This blend of salts results in Reef Buffer™ yielding a pK of roughly 8.6 in saltwater.\u003c\/p\u003e\n\u003cp\u003eThe pK of a buffering agent is equivalent to the pH around which that buffer most strongly buffers. One would presume, then, that the pK of a saltwater buffer should be 8.3; however, the multitude of organic acids produced by the inhabitants of a reef system forces pH downward to a much greater degree than in a non-reef, marine system. A buffer with a pK of 8.3 would end up yielding a pH more in the range of 8.0-8.2. Reef Buffer's™ higher pK (8.6) allows for greater pH stability in a reef system where the bioload is significantly more than in a fish only system. Competing products are not designed specifically for the reef environment, so their pK is too low (in most cases, pK 8.3). At this pK, the proper pH can never be reached in saltwater.\u003c\/p\u003e\n\u003cp\u003eReef Buffer™ will also raise carbonate alkalinity; however, when pH is not an issue,\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.seachem.com\/reef-builder.php\"\u003eReef Builder™\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eor\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.seachem.com\/reef-carbonate.php\"\u003eReef Carbonate™\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eshould be your first choice for a carbonate alkalinity supplement.\u003c\/p\u003e\n\u003cp\u003eSizes: 50 g, 250 g, 500 g, 1 kg, 4 kg\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"Reef Buffer 50 g \/ 1.8 oz - MAP Price $3.87","offer_id":56594797887791,"sku":"674","price":2.51,"currency_code":"USD","in_stock":true},{"title":"Reef Buffer 250 g \/ 8.8 oz - MAP Price $7.47","offer_id":56594797920559,"sku":"676","price":4.87,"currency_code":"USD","in_stock":true},{"title":"Reef Buffer 500 g \/ 1.1 lbs - MAP Price $12.75","offer_id":56594797953327,"sku":"673","price":8.31,"currency_code":"USD","in_stock":true},{"title":"Reef Buffer 1 kg \/ 2.2 lbs - MAP Price $23.16","offer_id":56594797986095,"sku":"677","price":15.08,"currency_code":"USD","in_stock":true},{"title":"Reef Buffer 4 kg \/ 8.8 lbs - MAP Price $73.24","offer_id":56594798018863,"sku":"679","price":47.71,"currency_code":"USD","in_stock":true},{"title":"Reef Buffer 20 kg \/ 44 lbs - MAP Price $282","offer_id":56594798051631,"sku":"671","price":183.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/9322\/6031\/files\/reef-buffer.jpg?v=1775950679","url":"https:\/\/openhouse.carolinaaquatics.com\/products\/reef-buffer","provider":"Carolina Aquatics Open House","version":"1.0","type":"link"}
