Can Calcium Be Too High In A Reef Tank? (Important Facts)

What’s the effect of too much calcium in a reef tank?

How do you know if you are getting enough calcium in your reef tank?

These are important questions because your coral will rely on this mineral to help them grow and survive.

If you don’t have enough of this Calcium in the water, you will soon find that you have some pretty sick coral in your aquarium.

If your corals don’t get enough calcium, they can become weak, brittle and eventually die.

Also, can calcium be too high in a reef tank?

It’s common to add have high calcium component in a reef tank, especially if you don’t have a proper testing kit. Too much calcium will affect the values and cause stress on your fish and invertebrates. It can also cause your fish to grow more slowly and swim erratically.

This is one of the reasons why many people decide to keep a reef aquarium.

The best way to figure out how much calcium your water has is to simply get a test kit and put some water into it.

You will then put a small amount of mineral into a bottle and pour a bit into each glass.

Let the kids sit in the water for a few days before testing the water again.

Testing calcium with test kits

testing kit for calcium in a reef tank

There are two different types of test kits that you can buy.

The first type that you want to look for is a test kit that you put in a bucket and then let sit in the water.

You want to make sure that the water gets at least 3 inches of water and that you are testing all of the same locations in your reef tank.

This way you can be sure that you get the same results when testing the water.

Another test kit that you can use is a kit that you can place in a bottle and then pour in a sample of the water from your reef tank.

You want to make sure that the bottle holds at least four ounces of water and that you have a sample of about 5 gallons of water in the bottle.

Then you simply pour a little bit of the test liquid into the bucket and wait for a day or so for the results to come back.

One of the best ways to answer the question about how much calcium is too high in a reef tank is to read the instructions that come with the test kits.

They will tell you exactly what type of water to test in, which aquarium types to look at and how long to allow the samples to sit in the water.

Once you have read the instructions, you will have the ability to determine how much you need to add to your reef tank.

If you need more than this amount, you may want to start making some adjustments to your water filtration system or the other parts of the aquarium.

Of course, there is another option that is available if you don’t have the ability to change the water in the reef tank yourself.

You can purchase a device that will add calcium to your water for you.

The problem with this option is that it can cost a lot of money and many reef aquarium shops won’t sell this device to you because of its expense.

Do I need to add calcium to my reef tank?

Many people assume that any kind of calcium you can get from your foods is sufficient. But is it?

Calcium is a vital mineral for a reef tank.

But when you add extra calcium to your tank, you may increase the hardness level in your tank and affect the growth and health of the fish in your aquarium.

Also, if you add too much calcium you can actually have a dead aquarium.

So how much calcium you need to add to your reef tank depends on what you are feeding your fish and what kind of environment you are living in.

Fish should be eating live food but there are other things you can add that will give your fish calcium.

This article is going to look at some of the things you can add to help your fish live a longer life.

There are two main sources for adding calcium to the water including rocks and corals:

These two types of food will supply the fish with different types of calcium and the different minerals and vitamins that they will require in order to grow and thrive.

Rocks and corals will provide a varied supply of calcium for the fish and will also have other beneficial minerals and vitamins in them as well.

Rock calcium

Rock calcium is usually calcium carbonate and can come in granular or powder form.

The powder form of calcium carbonate tends to be more absorbable by the fish and is often more readily absorbed by the reef tank. It can also cause the aquarium to become stagnant.

Coral calcium is obtained in two ways:

  • As a by-product of the algae that the coral produce
  • By eating the algae that the coral consume.

It’s important to make sure that the coral that you are adding to your reef tank is getting the same types of nutrients as the rest of the fish in your tank.

For example if your coral fish are eating algae, you need to make sure that the algae in their tank are getting the same types of nutrients.

Another thing you need to consider when using coral calcium is the environment of the aquarium.

Is the coral tank full of oxygenated water or is it an anoxic?

If the water is anoxic, it means that the fish and the coral will not get the same nutrients.

If this is the case then you will want to make sure that you only add the coral that can tolerate anoxic water.

Adding the extra calcium will also help to keep the temperature of the aquarium stable and will keep it in good condition.

It is also important that you do not overfeed your fish because when you add calcium.

Because the fish will get used to the extra calcium they will begin to eat the calcium from the bottom of the tank and it will actually start to lower the alkalinity of the water.

This means that the water in the tank is becoming acidic. You will need to ensure that there is plenty of oxygen in the tank before adding the calcium.

Finally it is also important to note that you should not add extra calcium to your reef tank if you are not sure about what you are doing.

Make sure that you are doing your research before you add the calcium.

How to reduce calcium in a saltwater tank?

So you are wondering how to reduce calcium in a saltwater aquarium.

Well there are several things that should be considered when doing this.

These include:

The most important thing to do is to remove all the plants that have lots of leaves on them.

This is why it is so important to avoid using them in your aquarium in the first place.

Leaves can contain a lot of calcium and will also build up over time in the aquarium.

It is also a good idea to keep the algae under control as well.

When I say that removing the leaves is important, this does not mean that you should totally get rid of them, but you should try and trim back the number of leaves you see.

If you don’t do this then the calcium will just continue to build up and eventually cause a problem.

Once you have removed all the plants then is a good time to begin checking your water and make sure that it contains very little calcium.

You can do this by using a scale and finding out what calcium concentration it contains.

A scale will give you the exact reading and this is the calcium that you should be aiming to keep at the correct levels in your aquarium.

If the tank you have is not planted then you may want to add some plant life in order to help get rid of the calcium in the water in your fish tank.

There are many different types of plants that are suited to use in this way and it is something that you should think about.

As you can see there are a number of options to reduce calcium in a saltwater tank and this is one of the ways that you can do this.

The only problem that you will probably have is trying to keep the levels as low as possible without actually harming the fish in the aquarium.

You can of course do a lot to reduce the levels of calcium that is present in your water by making sure that it stays cool and by keeping out of the water anything that is going to be eaten by your fish.

A lot of people will try and get the levels down to zero by using a potassium rich saltwater tank filter which is the best way to go.

If you have ever tried this, you will know that it is not going to be easy as the levels are going to build up so quickly and as soon as this happens you need to figure out a way to get the levels to zero again.

You should also make sure that you clean out your tank after each clean the filter to ensure that you get rid of any of the excess minerals that have built up in the water.

Another option for you to consider is to add more plants and this will help to prevent the levels from building up so quickly in your tank.

Of course, if you have a tank that has a lot of plants then this is going to take longer to achieve than if you are just adding one or two plants but they are still an option that you can choose to use.

What is the ideal calcium level in a reef tank?

What is the ideal calcium level in a reef tank? This is a question that many aquarists ask when they are first setting up their aquarium.

The amount of calcium is very important as it makes up the structure of the coral in your tank.

Without it the coral will not grow big and you will not have any real reef life in your fish tank.

The first thing you need to know is that the marine aquarium should not be too acidic.

This means that the water should not be around seven eight and even nine acidity levels.

So how do you know the ideal calcium level in a reef tank? You can find out a lot from reading a few books that deal with this subject matter.

Some marine aquariums actually have too much calcium in their water. If this is the case then you will find that the corals in your tank will become quite weak.

If this is the case then you will need to add some calcium carbonate. You can buy this at your local pet store or online.

If however you get the proper amount of calcium carbonate then the calcium in your tank will start building up and will help to make your corals stronger.

However, if you do not know how much is needed then it will be a good idea to look for a guide on calcium levels in reef tanks.

There are several guides on the market today that are able to give you a lot of advice.

Also, knowing how to properly balance the pH level in your reef tank will also help you in finding the right amount of calcium.

The pH level of your aquarium will be affected by the pH levels of your water.

If your pH level is lower than the level that it should be then you will not get the proper amount of calcium.

When it comes to finding out what the ideal calcium level is in a reef tank, it will be important that you do not get too many different numbers.

Too many numbers can confuse the whole thing.

Now that you know what is the ideal calcium level in a reef tank then you need to know how often you should be adding this.

It will depend on how long it has been since you last added more calcium.

If you keep adding this to your tank then you will find that your corals will not be able to build up the strength that they need to survive.


Reef aquarists that keep these tanks for very long periods of time will find that there are certain types of corals that can tolerate very little calcium in their water.

These corals will only need to have a low enough level of this mineral in their water to live on.

Some people will keep adding more calcium to the reef tank in order to keep the corals alive.

However, you can see that by keeping a small amount of calcium in your reef tank they can keep their corals healthy.
