How to Make Salt Water – Using different Methods

Saltwater is an essential part of our world that we rely on in so many ways. From the vast oceans that cover most of our planet to the small aquariums that we keep in our homes, saltwater plays a crucial role in the survival of aquatic life.

Humans also use saltwater for a variety of purposes such as swimming, surfing, and fishing. Whatever the case may be, this article is aimed at guiding you on different ways to make saltwater that’s safe for both you and the aquatic life that you care for. Let’s get started!

Materials Needed to Make Saltwater

To make your own saltwater, you don’t need a lot of fancy equipment. In fact, you probably have most of what you need in your kitchen right now! Here are the materials you’ll need:

1. Salt

This is the main ingredient in your saltwater mix, so it’s important to use the right type of salt. For example, if you want to use the saltwater for marine life, we recommend using aquarium salt, as it’s specifically formulated solely for that purpose.

2. Water

You can use tap water or distilled water for making saltwater

3. Measuring Cups 

You’ll need measuring cups to ensure that you add the right amount of salt to your water.

4. Mixing Bowl

You’ll need a mixing bowl to mix your salt and water together.

5. Spoon

You’ll need a spoon to stir your saltwater mix and ensure that the salt dissolves completely.

With these simple materials, you’ll be well on your way to making your own saltwater.

How to Make Salt Water

Below are four different methods to make Saltwater;

  1. Mixing Salt with Water
  2. Using a saltwater generator
  3. Collecting natural saltwater
  4. Using a desalination system

Let’s now pick them one after another.

Mixing Salt With Water (Method 1)

Follow these simple steps and you’ll be on your way:

Step 1: Boil Water 

First, you’ll need to boil some water. You can use tap water or distilled water for this step. Boiling water helps to kill any harmful bacteria that might be present in the water.

Step 2: Measure Salt 

Next, you’ll need to measure out the correct amount of salt. This is important because too much salt can harm your marine life, while too little won’t create the right environment for them. Use your measuring cups to measure out the appropriate amount of salt.

Step 3: Add Salt to Boiling Water 

Once your water is boiling, it’s time to add your salt. Slowly pour the salt into the water, stirring as you go. This helps to ensure that the salt dissolves completely.

Step 4: Stir Mixture Until Salt Dissolves

Keep stirring the mixture until all the salt has dissolved. It might take a few minutes, but be patient and keep stirring until the water looks clear again.

Step 5: Let Saltwater Cool Down 

Finally, let your saltwater cool down to room temperature before using it. This is important because hot water can be harmful to marine life or what you might want to use it for.

It’s that simple. Just make sure to use the right amount of salt and follow these steps carefully. The good thing about this method is that you can make this from your home.

Using a Saltwater Generator (Method 2)

A saltwater generator, also known as a saltwater chlorinator or salt cell, is a device that uses electrolysis to convert saltwater into a mix of sodium hypochlorite and hydrogen peroxide, which are both powerful sanitizers. The device is installed in your aquarium and requires a power source to operate.

The process is simple – the saltwater is pumped through the salt cell, where the electrolysis takes place, and the resulting mixture is returned to the aquarium. This process creates a continuous supply of fresh, clean saltwater that’s perfect for your marine life.

This saltwater generator method is very convenient as you don’t need to worry about manually making saltwater. However, it may demand a huge cost at the initial purchase of the machine as well as maintenance. 

Collecting Natural Saltwater (Method 3)

If you’re looking for a more natural approach to making saltwater, you can collect it yourself from the ocean or other bodies of saltwater. Here are other places to find natural saltwater: 

1. The Ocean 

This is the most obvious place to find natural saltwater. If you’re lucky enough to live near the coast, you can simply collect saltwater directly from the ocean.

2. Tide Pools

If you’re not near the coast, tide pools can be a great alternative. These small, enclosed areas are filled with saltwater and can be found along rocky shorelines.

3. Salt Marshes

Salt marshes are wetland areas that are periodically flooded by the tides. They can be a great source of natural saltwater.

While collecting Natural Saltwater, there are precautions you must take to make the saltwater suitable for use for you.

Precautions to Take When Collecting Natural Saltwater

  • Avoid collecting saltwater from areas with heavy boat traffic, as it may contain pollutants and other harmful substances.
  • Check local regulations to ensure that collecting saltwater is allowed in your area.
  • Always use a clean container to collect saltwater, and rinse it thoroughly with fresh water before use.

Tips for Making Saltwater 

Now that you know the basic steps to make saltwater, let’s go over some tips to help you make the best saltwater possible:

1. Use High-Quality Salt 

The type of salt you use can make a big difference in the health of your marine life. We recommend using aquarium salt, which is specifically formulated for marine life and contains the right balance of minerals and elements they need.

2. Measure Salt Accurately

Measuring the right amount of salt is crucial for your marine life’s health. Use your measuring cups and follow the instructions carefully to ensure that you’re adding the right amount of salt to your water.

3. Stir the Mixture Thoroughly

Stirring your saltwater mixture well ensures that the salt dissolves completely and is evenly distributed throughout the water. Take your time and stir the mixture thoroughly to avoid any salt pockets that could harm your marine life.

4. Use Distilled Water if Possible

While you can use tap water for making saltwater, it’s not always the best option. Tap water can contain harmful chemicals and minerals that could harm your marine life. If possible, use distilled water to ensure that your saltwater is as pure as possible.

Frequently Asked Questions

Can I Use Table Salt to Make Saltwater?

It’s not recommended to use table salt to make saltwater as it may contain additives and anti-caking agents that can harm marine life.

Can I Use tap Water to Make saltwater?

It’s recommended to use distilled or RO (reverse osmosis) water if possible, as tap water may contain chlorine and other harmful substances.

Can I use Natural Seawater for my Aquarium or Marine Environment?

Natural seawater can be used, but it’s important to collect it from a clean and safe location and test it for impurities before use. It’s also recommended to use marine salt or sea salt mix to supplement any missing minerals or trace elements.

How does a Desalination System Work?

A desalination system uses a process called reverse osmosis to remove salt and other impurities from seawater or brackish water. The water is passed through a semi-permeable membrane under pressure, which separates the salt and minerals from the water.


When deciding which method to use, it’s important to consider factors such as cost, availability of materials, time, and the intended use of the saltwater. For example, if you only need a small amount of saltwater for a science experiment or to clean your jewelry, Method 1 (using salt and water) may be the most practical and cost-effective option. However, if you need a consistent and reliable supply of saltwater for marine life or industrial purposes, Method 2 (using a saltwater generator) or Method 4 (using a desalination system) may be a better choice.

Understand the importance of using proper saltwater for marine life or whatever purpose you wish to use it for. The wrong type of saltwater can harm marine animals and plants, so it’s essential to follow proper guidelines and use the right type of saltwater for your aquarium or other marine environment.
