How to Measure the Hardness Water

Water hardness means how much calcium and magnesium are included in your water supply. When you can make sure about the water hardness, you can take some precautions to stay safe from risky Water. There have several problems that may occur from water hardness. For example, it might make a spot on the sink and dishes. 

Likewise, you have to use more soap to clean dishes if there have hardness in your water supply. Even sometimes water hardness may accumulate a level inside the pipe and block the pipe. Here are four common ways to measure the water hardness

  • Measured with the soap
  • Using testing stripes
  • Using a digital device

Measured with soap:

First of all, take 1 1⁄2 cup water in a glass bottle. It would be best if the bottle glass is transparent. As well as the bottle should have a cap. Now add ten drops of hand wash soap or liquid soap. After then I mixed the Water and soap with squeezing. Then shake the bottle properly. Lastly, let the mixture to settle down for one minute. 

You are now observed that the water bottle has some bubble on the top. You have to notice if the bubble amount is about 1 inch. It refers to this Water is soft to use and drink. On the other hand, if you don’t find any foam on the top of the bottle and the water looks cloudy, you have to understand that your Water has a hardness. 

Using a digital device:

You will get this device in an online shop or hardware shop. This device has on the button; you have to press it until the display has enlightened with light. Whenever you can see the display light, you can start the test. 

Now take a glass of Water and let the end part of the device sink into the Water. Check the display to know the hardness of your Water. If you get a hardness with more than 60 ppm, it indicates the Water’s hardness. 

Using testing stripes:

Testing stripes are most available among all other hardness test process. You will get it in any nearby local hardware shop or super shop. Do note that testing kit is made with a specific chemical mixed with the water mineral to find out the hardness. 

Hold the stripes into one cup of normal cold Water for a few seconds. Then take it off from the Water and notice on the changing color. You can compare the stripes color with the hardness color chart. 

How to determine the water hardness in the aquarium

Water hardness testing in the aquarium is slightly different. So, you need to manage individual testing kit for carbonate and general hardness. KH can measure the alkalinity of tank water. Alkalinity is very harmful to aquarium fish. At the same time, GH measured the amount of calcium and magnesium. 

In this test, it needs two test tubes. First of all, take an equal amount of water from the aquarium into both test tubes. Then add a few drops of GH and KH in each test tube. 

After then mix the test tubes water with few shakes and observed the water color changing. Lastly, compare the resulted color with the color chart. 

What is the ideal water hardness level?

Average all water sources have some hardness which has not any harmful effect on human health. But sometimes, the level of water hardness might increase much, which can be threatening for human health. That is why it is good to know the standard water hardness level. 

As per the general guideline of water classification organization, the soft calcium level is 0 to 60 mg/L. And the slightly hard calcium carbonate level is count from 61 to 120 mg/L. Also, the hard level of calcium carbonate amount is 120 to 180 mg/L.
