A couple of years ago, we published a method for making your own water recipes, using concentrated mineral solutions, diluted with deionised water, to make a range of waters with different hardness and alkalinity. This post updates this, with new recipes that allow you to easily target a specific GH and KH in your water.
幾年前，我們發表了一個自己製作水配方的方法，使用濃縮礦物溶液，用去離子水稀釋，製作出一系列不同硬度和鹼度的水。 這篇文章更新了這個，與新的配水方法，讓你更容易地達到特定GH（硬度）和 KH （酸鹼值）在你的水裡。
We』ve also added in a calculator that allows you to work out what will happen if you add minerals to existing water, rather than just deionised water. This will be useful to anyone in soft water areas who would like to remineralise their tap water, for example.
我們還增加了一個計算方式，可以讓你在現有的水中 計算出添加多少的礦物質，而不僅僅是去離子水，這對於那些生活在軟水的地區，希望將自來水再礦化的人來說，這個方法非常有用
The Recipes
You』ll need the following before you start:
Baking Soda – NaHCO3, Sodium Bicarbonate (not to be confused with baking powder)
Epsom Salts – MgSO4.7H2O, Magnesium Sulphate.¹
Deionised/Distilled/Ultra-pure water
Scales (accurate to 0.01g)
3 x ~1L water containers (preferably glass, and odour/residue free)
配水方法
在配水開始前你需要準備「小蘇打」——NaHCO3，碳酸氫鈉（注重不要和小蘇打混淆）
鎂鹽——MgSo4.7H2O，硫酸鎂
去離子/蒸餾/超純水稱（精確到0.01g）
3個1升裝的水容器（最好是玻璃容器 無異味 無異物）
The Buffer Solution
Dissolve 1.68g of sodium bicarbonate in 1L of deionised water. This creates a solution with a KH (as CaCO3) as close as we can get to 1000ppm.
緩衝溶液
1.68g碳酸氫鈉溶解在1升的去離子水中，這就得到了溶液KH（不包括碳酸鈣）這就接近我們能夠得到的1000ppm
The Hardness Solution
Dissolve 2.39g of Epsom salts in 1L of deionised water. This creates a solution with a GH (as CaCO3) of 1000 ppm.
硬水製作
2.39克的硫酸鎂溶解在去離子水中，這就得到了GH溶液、（不包含碳酸鈣）在1000ppm
Create Your own Water Recipe using Deionised water
Using these two solutions with deionised water is very simple. To get your desired KH and GH, you can simply use that number of mls of each solution, then make the total volume up to 1L with deionised water.
自己配水的配方
使用去離子水
使用這兩個解決方案與去離子水是非常簡單的。 為了得到你想要的 KH 和 GH，你可以簡單地使用每種溶液的毫升數，然後用去離子水使總體積達到1L。
Mineralise Pre-existing Water
If you prefer to add hardness or buffer to existing water, perhaps to take advantage of the calcium or other minerals already in the water, then you can use this calculator to work out what the final KH, GH, and TDS of your water will be. This is helpful if just want to boost the hardness of your favourite bottled water, for example, or to mineralise your tap water if you live in a soft water area.
礦化預先存在的水
如果你喜歡增加硬度或緩衝現有的水，也許利用鈣或其他礦物質已經在水中，那麼你可以使用這個計算器計算出你的水的最終 KH，GH 和 TDS。 例如，如果你只是想提高你最喜歡的瓶裝水的硬度，或者是你住在一個軟水區域，使你的自來水的礦物質化，這是一個有用的方法。
To use this calculator, measure the KH and GH of your existing water (and optionally your TDS), then put these numbers into the calculator along with the amounts of each solution you plan to use.
要使用這個計算方式，請測量您現有的水(可選的是您的 TDS)的 KH 和 GH，然後將這些數字連同您計劃使用的每個解決方案的數量一起放入計算方式中。
You』ll see that adding 10ml of a solution doesn’t simply increase KH or GH by 10, like it does with distilled water. This is because the solutions themselves dilute the water that you started with. By tweaking the amounts of each solution that you use accordingly you should be able to work out what amount will get you your target GH and KH.
你會看到，加入10毫升溶液並不像加入蒸餾水那樣簡單地增加 KH 或 GH 在這10毫升溶液中。 這是因為溶液本身就稀釋了開始時的水分。 通過調整每個解決方案的數量，你使用相應的，你應該能夠計算出什麼數量將得到你想達到GH和 KH
Why are these RecipeDifferent?
Our previous solutions were designed to give you 1g/L of magnesium or bicarbonate ions, respectively. However, this is not the way that we usually measure hardness and alkalinity.
Rather than give the concentration of the ions directly, both hardness (GH) and alkalinity (KH) are usually measured in calcium carbonateequivalents. In other words, it tells you how many parts per million of calcium carbonate you would have, if all the hardness or alkalinity was due to calcium carbonate alone.
我們之前設計的解決方案是分別給你1克 每升的鎂或碳酸氫鹽。 然而，這不是我們通常測量硬度和鹼度的方法。
而不是直接給出離子濃度，硬度(GH)和鹼度(KH)通常測量在碳酸鈣當量。 換句話說，它告訴你如果所有的硬度或鹼度僅僅是由於碳酸鈣 （導致的），那麼你將會得到百萬分之多少的碳酸鈣。
It’s measured this way because simple drop test kits can’t distinguish between calcium or magnesium ions, so it’s easiest to assume it’s all calcium. This means that when we start using magnesium or sodium salts to tweak the water, we need to do a bit of maths to convert those amounts into CaCO3 equivalents.
To make it easier for you to experiment with different hardnesses, we』ve altered the recipes to aim for a specific KH and GH instead. This means that you can easily target any GH or KH you like, with no conversion required.
之所以用這種方法測量，是因為簡單的沉澱試驗裝置無法區分鈣離子或鎂離子，所以最容易假設它們都是鈣離子。 這意味著當我們開始使用鎂或鈉鹽來調節水時，我們需要做一些數學運算來將這些量轉換成碳酸鈣當量。 為了讓您更容易地實驗不同的硬度，我們改變了配水方式，以特定的 KH 和 GH 為目標。 這意味著，沒有轉化要求，你可以很容易地得到任何你想達到的GH 或 KH 。
A Note about TDS
Note that the TDS given by this calculator might not be exactly the same as the TDS you would see if you measure the resulting solution with a TDS meter. This is because TDS meters assume a certain ratio of all the ions in the water, and by adding these solutions, we’re messing with that ratio.
關於 TDS 的注意: 這個計算器給出的 TDS 可能與如果使用 TDS 計量器測量結果的 TDS 不完全相同。 這是因為 TDS 儀器假設了水中所有離子的一定比例，加上這些溶液，我們就破壞了這個比例。
A Plea for Mathematicians
It should be possible to set up a pair of simultaneous equations to work out exactly what amounts of each solution to use to reach a target KH and GH when working with pre-existing water. However, setting these equations up in a spreadsheet is beyond us here at BH! If any mathematician readers would like to help us solve this problem and create a more powerful calculator, then we』d love to hear from you.
¹ The 「.7H2O」 part refers to the fact that water forms an intrinsic part of the crystal form of this salt that you can buy in the shops, which is the clear crystals called Epsom Salts. Each magnesium sulphate molecule is surrounded by seven water molecules in this type of crystal. We’re specifying this here, as the weight of the water in the crystal affects the calculations.
返回文章頁面數學家的請求譯者: liuliuliu 數學家們應該可以建立一對方程組來計算出在使用已存在的水的情況下，每種溶液到達目標 KH 和 GH 的精確用量。 然而，在電子表格中設置這些方程式超出了我們在 BH 的範圍！ 如果任何數學家的讀者願意幫助我們解決這個問題，並創造一個更強大的計算器，然後我們很樂意聽到你的聲音。 1. 「 . 7 H2O」部分指的是這樣一個事實，即水是這種鹽結晶形式的固有組成部分，你可以在商店裡買到，這種鹽就是被稱為硫酸鎂的透明結晶體。 在這種類型的晶體中，每個硫酸鎂分子被7個水分子包圍著。 我們在這裡指出這一點，因為晶體中水的重量影響了計算。
