汉娜硝酸盐检查器是我们最喜欢的新水族馆工具之一，用于测量礁石罐中的营养素，但唯一的限制因素是获得足够的官方Hanna硝酸盐试剂。我们一直在仔细弄清哪些储罐最值得进行非常准确的硝酸盐测量值，直到我们发现一些创意的礁石已经弄清楚如何将API硝酸盐试剂与Hanna硝酸盐检查器结合使用。
使用API试剂的协议近似于如何执行Hanna硝酸盐测试，尽管您确实必须考虑两种液体试剂，而不是Hanna官方试剂的单个干粉。We feel it’s important to stress that the API Nitrate reagents only qualify as ‘usable’ with the Hanna checker as the results are not exactly the same but they are in the ballpark of values, which is still a huge improvements over having four or five shades of fuschia pink to discern with our fallible, analog eyes.
我们使用Hanna检查器的API试剂进行了大约30次测试，其营养素水平为0至65 ppm，平均偏差约为汉娜官方试剂，其中有一些大问题。虽然平均差异是通常around 10%, sometimes we’ve seen the values turn out exactly the same at 5ppm, other times the API will be 100% higher with the Hanna reagents giving us a value of 1ppm while the API reagent gives us 2ppm.
除了没有为API试剂设计的Hanna检查器之外，我们还无法确定是什么原因导致某些测试相同，而其他测试则更高或更低。We do believe that using the API reagents with the Hanna Checker is still better than trying to eyeball the precise color, but if you’re trying to quantify a precise nitrate level of your aquarium’s nitrate consumption or production you’ll still want to go with the official Hanna nitrate powder reagent.
