What is Best Reef Salt?
Reef salt is the magic ingredient in your saltwater aquarium.
This is what makes the water in your aquarium salty and helps you reproduce the reef’s natural waters.
Reef salt is made up of all the salts and trace elements found in seawater such as: chloride, sodium, magnesium and calcium.
These salts will form the salinity of your aquarium (ocean salinity is typically 35 PPT). Salinity is measured in parts per thousand (PPT) which describes the concentrations of dissolved salts.
This means that, on average, each kilogram of water contains approximately 35 grams of dissolved salts. with an average density of 1,025 kg / L on the surface. Sodium chloride is the most abundant sea salt with a small percentage of magnesium and potassium.
Knowing the salinity concentrations in your water is very important, especially during water changes. You don’t want to change the levels too much and poison your fish.
As the water in your aquarium evaporates, the salinity increases. This is important to know when replenishing the water, as you can only add fresh water because it will mix with the higher salinity waters in the tank and return the salinity levels to normal.
You will find that different mixtures of different things go out, from corals to invertebrates to fish. These mixtures have different salts and concentrations of trace elements vital to keep marine life healthy.
Corals and invertebrates prefer higher concentrations of carbonate and calcium and buffers that help build their skeletons and shells.
Having a nicely colored tank is one of the best things to look at and show off to your friends, which is why these mixes often contain micro and macro nutrients to enhance the colors of your fish.

Does your aquarium need reef salt?
Reef salt is best added to tanks that have fish and animals found on a coral reef.
Once you’ve decided on the animals you want, you need to build the perfect environment for them, from the tank substrate to the decorations. But the most important element in saltwater aquariums is water.
Normally, the conditions of ocean waters are variable, with different temperatures and salinity.
Variations in temperature and salinity create different densities of water that change with different streams of water. The density of water can change so much between different currents that oceanographers use it to track water movements .
Due to the amount of life that surrounds ocean reefs, these environments are often nutrient-limited, meaning that the waters have very little nitrate and phosphorus. Therefore, it is important to understand if your saltwater tank needs specific reef salt.
It is very important to start from the beginning, with the water. Household water supplies are generally unsuitable for saltwater aquariums as nitrate and phosphate levels are very high.
Before adding water to your tank, you must purify it to remove any dangerous contamination and toxic compounds.
It can also have a combination of reverse osmosis and deionization known as RODI units.
Once you’re done with the water, the salt will be a lot easier. Different brands often have slightly different chemical formulas that alter the amount of salts and trace elements present in the water.
Like most things about fishing, there is no right or wrong answer. You will need to do your research and find the best combination that suits your unique setup.
Reef salt vs sea salt
Reef salt, sea salt, crystals, there are many options to choose from. But what is the difference and what is best for your tank?
Each of these is a different combination of salts. To understand the differences correctly, you need to look at their chemical composition.
Reef salt has a higher concentration of calcium, iodide, and magnesium than sea salts.
They both have very low nitrate levels and if tested they should give a negative result.
They are all intended to mimic the natural condition of seawater, but reef salts have been designed for coral reef environments while sea salts have been designed for a more general marine environment.
Sometimes these salts are interchangeable, and you can use either of them as long as the salinity stays around 35 PPT.
Although salinity is not everything, reef salts will also help maintain correct alkalinity and pH with essential and non-essential components such as cadmium, silicate, nitrate, phosphate, beryllium and arsenic.
Calcium is a very important aspect for coral reefs – without this element, corals and shells cannot calcify and build their own skeletons and protection.
Therefore, the chemical composition of reef salts aims to replicate the natural condition of a reef system in an enclosed saltwater aquarium so that its inhabitants feel at home.
How to choose the best reef salt?
Choosing the best reef salt is one of the biggest dilemmas.
It all depends on the organisms you want in your tank.
Different brands have slightly different chemical compositions and it all comes down to how the fish reacts to the mix.
You can start with one type of mix and switch to another to find the best balance.
The main thing to consider when choosing a mixture is the content of phosphates and nitrates; both must be negative and insignificant.
Coral reef ecosystems are limited in nutrients due to the amount of life they support, so animals are used to low concentrations of nitrate. If these concentrations increase over a long period of time, it will be harmful to your fish.
Other things to consider is its composition: calcium, magnesium, and alkalinity are good starting points.
- Calcium is one of the most important elements, as it is one of the basic components of reef organisms. The recommended concentration is 400 PPM.
- Magnesium is one of the most abundant trace elements in seawater and balances the alkalinity of the water in your tank. 1250 PPM is the recommended concentration for closed salt water systems.
- Alkalinity can greatly affect the pH so it is important to monitor it. Recommended levels are 8-11 dKh for saltwater aquariums.
Look for the general levels of the items listed above for a good start.
How Much Reef Salt Do You Need?
To understand how much reef salt you need, we have to talk a bit about salinity and what makes seawater so salty.
The oceans cover approximately 70% of the Earth’s surface containing 97% of the water present on Earth. The other 3% is contained in freshwater systems, glaciers and polar caps.
If the planet were to dry up, the salt contained in the oceans would cover us to a depth of 5 feet.
Therefore, when setting up a saltwater aquarium, salt is critical to a healthy and successful environment.
Salinity varies throughout the ocean depending on: depth, evaporation, and many other factors. Generally, this can range from 31 to 38 PPT. Salinity is usually around 35 g per liter of water. As discussed earlier, grams per liter is the same as saying PPT.
This means that in each liter of water I need 35g of salt. This equates to approximately 4.7 ounces of salt per gallon of water. However, this could change for certain brands, so be sure to read the label on your reef salt.
How is reef salt mixed?
The reef salt mix varies from product to product, so you must follow the directions with each product.
However, here is an overview with some helpful tips as well.
First of all, make sure the water you are using is correct. Your tap water is rich in nitrates and phosphates and also contains other invisible things that are harmful to the inhabitants of your tank. Choose the best way to purify the waters and then add the reef salt.
You should always mix the water before adding it to the tank, to allow the salts to dissolve easily. When mixing reef salts, always remember the rule of thumb of 35 g per liter of water or 4.7 ounces per gallon.
Test and check the salinity while adding the salt to make sure you get the correct concentration. You must add more water to lower the salinity. Or if you need to increase the salinity, add more salt.
You can use some simple math to be more precise.
First measure the salinity you already have.
For example, it could be 31 PPT per 100 liters of water. You still have 4 PPT to go to the final concentration of 35 PPT. Therefore, 4 grams (the same as PPT) * 100 L = 400 grams of salts.
On the other hand, if you have a salinity of 40 PPT in 100 liters of water you will have to add about 115 liters of water. This is calculated as (40 PPT / 35 PPT) * 100 L = 114.9 L.
Just keep in mind that when you add more salt to your aquarium you are also altering the alkalinity, calcium, magnesium, and other components.
To accurately measure salinity, you can use a refractometer or a hydrometer.
Reef Salt Vs Marine Salt
When these two are compared, it is observed that reef salt has higher levels of calcium, iodide and magnesium than sea salt.
There are still some similarities, such as both types of salt will be negative for nitrates, as nitrate levels are negligible.
What Is The Best Reef Salt To Use?
If you are new to buying the best reef salt for your aquarium then you should go for instant ocean reef crystals reef salt.
This salt comes from a superior brand that makes the best rated reef salt for use in an aquarium. In addition, salt has more important compounds such as calcium that promote the growth of large and small corals. You will always get the best coralline algae development when using this product.
The manufacturer also included trace elements that will ensure the vigorous growth of the corals. With the metal detoxifiers also used in this salt, you can be sure that the heavy metals found in your domestic water supply will be easily removed.
What Is The Best Reef Salt Mix?
The question of which is the best reef salt mix is common in many forums.
Many people are happy to give their opinion on what makes the reef salt mix, but the important thing is that you understand the basic components of the best mix.
The first thing to consider when choosing a reef salt mix will be the differences between the different brands. All brands will have a label showing what to expect from their sea salt.
The composition of the salt will also be shown on the label. The composition can vary widely from brand to brand, but some also have common ingredients. The varying composition of the salt mixture will create the differences between one brand and another.
If you want to end up with the perfect match, there are a few things to keep in mind when making your decision. Common parameters to compare between brands include the amount of calcium, magnesium, and alkalinity.
The calcium compound is the most important component in reef salt. Corals and other types of invertebrates need it to build their skeletons. The recommended concentration for good results is 400 ppm. PPM stands for part per million.
Magnesium is another important mineral to have in reef water. It is often considered to be the most abundant trace mineral found in salt water. Magnesium will work together with calcium to help balance the alkalinity of the aquarium water. The recommended concentration is 1250 ppm.
Alkalinity is going to affect the pH level of the reef tank. With the addition of the salt, you can expect the water to become more alkaline. You need to take alkalinity into account to make sure you understand the level of bicarbonate in your water. You may have to adjust the alkalinity where possible. The alkalinity of the saltwater aquarium is recommended to be 8-11 dkh.
Now back to the question. From the details above, you want to have calcium in the range of 400 ppm, magnesium 1250 to 1400 ppm, and alkalinity maintained between 8 and 11 for the salt mix.
How Much Reef Salt Per Liter?
This will vary from brand to brand, but in most cases, it will be 35g per liter of RO water. You can always check the label for the manufacturer’s recommendations.
How To Mix Reef Salt?
The first thing you will need to do is get the best sea salt for your aquarium. You can easily buy it from a nearby store that sells aquarium-related products. Most of the time, you will get the synthetic reef salt dry so that you can mix it with water.
The next thing is to gather all the supplies needed for the job. You will need water to mix, and the best option is to use deionized water for this process. You can only use tap water if the water quality is excellent.
You can buy deionized water at a store near you. Additional supplies for the process include a clean bucket, submersible heater, stirring tool, hydrometer, and floating thermometer.
Fill the container with deionized water and add salt in the correct amount according to the manufacturer’s directions. Each manufacturer offers information on how much water should be used to dissolve a certain amount of salt. Let the mixed saltwater settle overnight before you can add it to your aquarium.
Keeping the reef aquarium in good condition goes a long way when it comes to making sure you have the best coral in your tank. Now that you know more about the best reef aquarium salt, go ahead and choose one for your aquarium.
Make sure you understand the composition of each type of salt before buying. Having the right type of composition goes a long way in choosing the best salt for your marine aquarium.
Within a few weeks of using the proper reef salt, you should be able to see some differences. The differences mean that their corals look even more alive and better.
