多年来,礁石水族馆的爱好已经越来越多地对我们的珊瑚礁坦克的许多方面进行了分析。我们使用光合活性辐射的微醇测量光水平,使用ICP测试服务发送水样以进行超精确的化学测量,并且我们大多数人使用高纯度添加剂接近药物级。新万博登录网址
尽管我们越来越科学和精确的珊瑚礁水族馆的进步,但我们认为缺乏的一个关键因素是知道实际体积我们的礁石水族系统。一个典型的180加仑水族馆的尺寸为72 x 24 x 24英寸,使其41,472立方英寸,实际上可以工作至179.5加仑。
但是,这些是外部尺寸,因此,如果我们减去半英寸的玻璃厚度,我们会得到37,559立方英寸或162.5加仑 - 您的八十实际上,将其接近160加仑的水,但这就是您将其填充到顶部!减去另外1.5英寸,现在我们到达152加仑,是水量的15%less除了标称储罐的额定值,我们甚至还没有考虑到内部或外部溢出,所有岩石,沙子,珊瑚和是的流离失所,甚至是鱼的流离失所。
Add some volume for your sump and pipework, water in the skimmer and reactors, then remove some volume for the pumps, heater and biomedia, and now you are left with a situation that most reefers are in, simply not really knowing the actual volume of water within their aquarium displays and systems. How can we even aspire to do anything close to chemically precise in our aquariums if we don’t even know how much water we’re working with?
As you know we’ve been building up an all-new澳大利亚n LPS aquarium using the Cade Pro Reef S2 900, and are just at the point where all the rock and equipment is inside and ready to be salted up. This tank is described as having a total system volume of 104.9 gallons but if you don’t look closely at the spec sheet you’ll miss the part about the built-n ATO reservoir containing 6.3 gallons bringing the actual working volume to 98.6 gallons, but again only when it’s filled to the very brim.
We have long since wondered how we could accurately calculate the actual volume of water of our aquariums after they are totally set up and populated. There’s probably a way to add a very precise measure of some trace element like strontium and test the water using ICP to calculate the volume based on the rise in concentration, but in the meantime we have devised a simple method to answer this question in a new aquarium that doesn’t yet have any livestock inside of it.
与我们的坦克ProReef S2 900完全是否构成, all equipment in place and running filled with freshwater, we decided to use the five gallon pre-measured bags of Two Little Fishies AccuraSea 1 salt mix to calculate water volume using chemistry, and math. In our case it was important to specifically use these pouches of pre-measured salt which we know to be 618 grams when it is packaged in a dry environment, because over time moisture can and does seep through the bag. You could also replicate this method if you have a precise scale and access to super dry salt, like from an unopened bucket, but you’ll also need an accurate, freshly calibrated conductivity meter to take your measurements.
For our experiment we used the汉娜盐度测试仪, freshly calibrated, and began by measuring the salinity (conductivity) of the freshwater in the tank which came out to 0.2 parts per thousand since the water and Marco Rocks added some initial dissolved solids to the water. We added one,五加仑袋1and let it dissolve completely for about 30 minutes at which point we measured a salinity of 2.1 ppt.
Subtracting the initial salinity, we get a rise of 1.9 ppt and since we know we added 618 grams of salt, we can start crunching the estimated volume by this method. Density is mass divided by volume (D=m/v) and since we know two of these terms, we can rearrange the equation to calculate volume v=m/D. Using this method, 618g/1.9ppt = 618g/0.0019 = 325,263 grams. 1ml of (fresh) water weighs one gram, giving us 325,263 ml, or 325.3 liters, which works out to 85.9 gallons.
We repeated this process two more times, adding packets of pre-measured AccuraSea 1 salt and measuring the subsequent rise in salinity and calculated 88 and 89 gallons, but we know there’s a small degree of inaccuracy in our calculation which doesn’t take into account the mass of salt already in the water. Nevertheless, this is a much smaller degree of uncertainty than we started with, and we now know with a great deal of confidence that our tank目前持有86至88加仑的水,占坦克,水箱,管道,岩石工程,流离失所等的含量。
As we add corals and fish, more and more water will become displaced over time, but we’re glad we arrived at a precise measure now because we won’t be repeating this salinity measurement method once the tanks are filled with delicate livestock. We believe there is a method for a precise dose of a trace element and a pair of ICP tests to help arrive at similar, calculated volume in established reef tanks because of all the things that should be easy to知道about our reef tanks, the actual water volume should be one of them.
