Best Reef Salt Buying Guide

If you’re a keen reef aquarist, the health of your coral will be at the forefront of your mind. One way to ensure that your coral gets the nutrition they need in order to maintain good health is to add reef salt to your aquarium.

With so many different products on the market, it may be tempting to just opt for the first reef salt that you stumble across. But wait - you’ll want to ensure that this reef salt is perfect for your reef aquarium.

We’ve put together a few points for you to look for in your reef salt before you commit to buying it.

Just like many different types of fish, your coral can be sensitive to the things you put in your aquarium, and it will be devastating to discover you’ve opted for the wrong product.

Take a look at the points below, and you’ll be armed with all the knowledge you need for sourcing the right reef salt for your reef aquarium.

Designed for reef aquariums

Take a look at what exactly your chosen product has been designed for. If it says it’s been specifically designed with reef aquariums in mind, you’ll know you’re onto a winner.

That’s because it will have been specially designed so as to create the perfect environment for your reef.

If you opt for a product that hasn’t been designed for use in a reef tank, then this may have a detrimental effect on the coral in your tank - as well as any fish you may have in there, too.

Major, minor, and trace elements

Look for a reef salt that will contain all the major, minor, and trace elements your coral needs in order to grow strong and healthy.

This will include elements such as calcium, magnesium, and potassium. Many corals need these elements in order to thrive, so as long as your chosen product has these ingredients, you’ll be giving them the helping hand they need.

If you opt for a reef salt that says it contains all the major, minor, and trace elements, then you can rest assured that your reef will have everything it needs to flourish.

Detoxifies metals

A lot of tap water can come with heavy metals in it, which can impact on your coral and fish if these haven’t been removed before you add them to your tank. The good news is that there are several reef salts that can detoxify and neutralize any heavy metals your tank water may have.

This will help to create a more ideal environment for your coral and potentially fish, and will allow everything you have in your tank to thrive.

Stabilizes pH after mixing

One of the most important factors in creating the ideal environment for your coral is the pH of your water. If it’s too acidic or too alkaline, this will negatively affect anything you’ve got in your tank, and could potentially kill off any precious coral that you are trying to cultivate.

Look for a reef salt that says it has enhanced buffer levels. This means that they stabilize the pH quickly after mixing, so you’ll know that it’s safe to add to your tank.

Remember to check the pH of the mixed water before you add it to your tank, though, just to be on the safe side.

Type of coral

If you want a variety of different corals in your reef aquarium, they may all need different types of nutrition in order to survive and thrive.

Take a look at what kind of nutrients your chosen reef salt is able to provide them.

If your reef salt comes with extra calcium and magnesium, it will be ideal for supporting softer corals that can be trickier to look after.

A well-rounded reef salt will give you more choice when it comes to the types of coral you can introduce into your reef aquarium.

Frequently Asked Questions

What is the perfect salinity for a reef tank?

The perfect salinity that is recommended for your reef tank is between 1.024 and 1.025.

If your tank is slightly above or below these measurements by one or two points it should be fine, but these measurements would be the optimal condition for your reef tank.

What happens if salinity is too high?

If the salinity of your reef tank is too high or too low, this will impact negatively on your coral. You should try and keep it between 1.024 and 1.025. If the salinity is too high, you can bring it down by doing a few water changes.

Make sure you have a proper filter in place too to ensure a healthy ecosystem in your aquarium.
