Thus, a measurement deviation of up to 1.5ppt is possible, which can have a significant adverse effect on coral growth and coloration.\u003c\/p\u003e","brand":"Red Sea","offers":[{"title":"Default Title","offer_id":57054632542539,"sku":"REDSEA-REFRACTOMETER","price":52.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/7065\/4027\/files\/l_a_large-red-sea-refractometer_82.jpg?v=1776424165","url":"https:\/\/krakencorals.co.uk\/products\/red-sea-seawater-refractometer","provider":"Kraken Corals","version":"1.0","type":"link"}
