Reef and marine tanks typically run between pH 7.8 and 8.5, so a pH 9 reference point brackets that range far better than pH 4 does.\u003c\/p\u003e\u003ch4\u003eDo I need both the pH 7 and pH 9 fluid?\u003c\/h4\u003e\u003cp\u003eYes, for an accurate two-point calibration. A single-point calibration only confirms one spot on the scale; using both fluids lets your probe correct for any slope error across the range it actually reads.\u003c\/p\u003e\u003ch4\u003eHow long does one bottle last?\u003c\/h4\u003e\u003cp\u003eThat depends on how often you calibrate - Aqua Medic recommends roughly every four weeks - and how much fluid you discard per session, but 60 ml comfortably covers several calibrations.\u003c\/p\u003e","brand":"Aqua Medic","offers":[{"title":"Default Title","offer_id":55285032059171,"sku":"AM230009","price":35.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/12255_test-fluid_22619a89-4e0a-48d8-b4a3-df3f90843ab8.jpg?v=1786066073","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/aqua-medic-ph-9-test-fluid-60ml","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
