在非常基本的水平上，一些礁石了解二氧化碳，碳酸盐，碳酸的相互作用。但是，我们不太确定盐水水产师真正了解这些化学物质如何影响pH和碱度，尤其是它如何与我们家庭水族馆中珊瑚的增长率相关。
Like so many aspects of keeping marine aquariums, coral growers can wax poetically about the esoteric needs our corals have for exotic trace elements, uncommon amino acids and how they react to specific wavelengths of LED light – but when it comes to the fundamentals of aquarium chemistry like salinity, pH, and temperature, not so much. Even if you think you really understand the carbonate chemistry of saltwater and how it dictates the growth rates of our corals, you owe it to yourself to watch at least some of this new program from NOVA.
Entitled ‘Lethal Seas’, this documentary raises the alarm about the rate of ocean acidification in our oceans, and how this is already impacting marine life. The program explores how some oyster farmers have basically started adding kalkwasser to incoming seawater in order to restore the carbonate hardness for their baby oysters.
同时，在巴布亚新几内亚珊瑚礁生态学家Dr. Katharina Fabricius，研究在米尔恩湾的某些珊瑚凉亭中冒泡的二氧化碳的自然渗漏，以及在珊瑚附近形成苏打水的酸化作用。Fabricius博士在Reeefers中被称为著名的作者软珊瑚and Sea Fans，但是在此视频段中，我们可以看到酸性水与对鱼类行为的负面影响之间的直接联系，以及对珊瑚生长的负面影响。
虽然我们的珊瑚种植者确实注意通过平衡稳定的集中度以保持pH值carbonate hardnesswe call alkalinity, we really should be thinking of CO2 as a pollutant in our aquariums, and minimizing this gas from our aquarium water in order to promote better and faster coral growth. Several parts of this NOVA Lethal Seas segment really explain why and how CO2 impacts the growth of basically anything with “shell”, including corals, so do yourself a favor as an aquarist and give your reefer brain a little lesson and refresher on the carbonate chemistry of seawater.
