The Pool Mineral System: What you should know about it

For many people, chlorine and bromine are the methods they utilize to sanitize their pool. However, as you may well know, there are other options available. On this page, we are going to take a look at the idea of a pool mineral system, while highlighting some of the pros and cons of this method of sanitizing your pool. This may help you to decide whether it is the right option for you, or not.

What is a Pool Mineral System?

Just like bromine and chlorine, the purpose of a pool mineral system is to help to sanitize your pool. Although, it is going to do it in a slightly different way. The method is a bit more ‘natural’. There will be a few different minerals in the pool mineral system, and the quantities (and the ones that appear) will be dependent on the system that you purchase.

Nearly all of them are going to use silver. The purpose of silver is to help to kill off any bacteria in the pool. It often does a far better job at it than chlorine or bromine too. Don’t worry. Just because there is silver in a pool mineral system, it doesn’t mean that the system is going to be expensive. There isn’t that much silver. Just enough to keep the water clean.

There will also likely be a bit of copper added to the pool mineral system. The purpose of this is to help kill the algae in the pool. That being said, it is unlikely to kill off all of the algae. This is why you still need to use bromine or chlorine. Those two chemicals will act as a ‘back-up’.

There may be other minerals added on top of this, but nearly every pool mineral system will include those two minerals. The only other one which seems to appear quite often will be limestone. This can help to keep your PH at a neutral level. This is important, particularly if you are using chlorine. It is going to make your pool a bit easier to maintain.

How to use a Pool Mineral System

One of the first decisions you will need to make when using a pool mineral system is how to deliver the product into the pool. Honestly, the choice is up to you. It is really going to be about simplicity and how you want to install it. Neither method is particularly better than another:

  • In-Skimmer: most people find that this is the easiest system to install. It just goes into the skimmer basket. You barely have to replace it too. Every few months, at a push.
  • Floating Dispenser: if you do not mind having something floating in your pool, then a floating dispenser may be ideal for you. You just put in the water and you are done. Simple.
  • Inline System: this just connects up to the system. You will need to plumb it in, but it is one of the best dispensing systems. You will need to change the cartridge a bit more often, though.

Once you have managed to select the option you want to deliver the water, it is up to you to start preparing the pool. For this, you are going to need to get your bromine or chlorine levels to fall. Some people will start off with a fresh pool, but you can wait for them to fall if you don’t want to refill a pool if you wish. Your levels should be at the following points:

  • Chlorine: 0.5 ppm
  • Bromine: 1 ppm

Once the levels have fallen this far, you need to check the water hardness:

  • Water hardness should be 225ppm
  • If you have a pool that is lined with plaster or concrete, then this can be 275ppm.

The next step is to test the water for metals. You do not want them to be too high. If they are, then you need to purchase a product that will cancel out this metal. This will all be dependent on the metal that is filling up your pool (copper is especially bad for pool mineral systems). Your pool supplier will be able to tell you what to do.

Finally, you need to bring the PH levels to between 7.4 and 7.6.

Once you have done all of that, your water should be ready to have the pool mineral system added. The way in which you add this to the water should be dependent on the product you have purchased. This means that you will need to read the instructions. It is important that you do not add too much to your water. If you do, then 

Other than this, it is just a case of keeping chlorine or bromine levels in sync and, of course, making sure that the water is fine. Basically, this is going to be your normal checks. Chlorine and bromine should never go beyond the ppm that we mentioned earlier. This should be a little bit easier to maintain than the system that you were using previously.

Pros of a Pool Mineral System

So, now you know a little bit about a pool mineral system and how to use it, let’s take a look at some of the reasons why you may want to consider using this method of pool sanitization. 

The Pool Water is Softer

The water in a pool sanitized with a pool mineral system will be so much softer on your skin. It doesn’t dry out your skin so much, and it just feels that much better to be inside. When you are wearing swimwear, you will also notice that the water won’t stain your clothing, or cause it to fade. Generally speaking, a pool mineral system is better to swim in for the long term.

The Pool Will Smell Better

Yes. You will still need to use some chemicals in your water when you use a pool mineral system, but you will have to use fewer. This means that your water is not going to have that ‘chemical’ smell.

Everything In Your Pool Will Function Better

This is due to the soft water. There will be less pressure put on your pool equipment e.g. filters and pumps. This means that you will not need to repair or replace them anywhere near as often.

Easier to maintain

A lot of people report that a pool mineral system is easier to maintain. This is because you need to do less to keep the chlorine or bromine levels about right. All you really need to do is think about replacing the pool mineral system cartridge, and this shouldn’t take too long and it probably doesn’t need to be done anywhere near as often as you think (it will be dependent on the product you have purchased). This means that your water will remain better for longer.

Cons of a Pool Mineral System

As brilliant as a pool mineral system may sound, you do need to be aware that there are going to be a few downsides. This may mean that sanitizing your pool like this may not be the best method for you.

You won’t be able to ditch the other pool chemicals

Yes. You will be using less chlorine or bromine when you have a pool mineral system, but this does not mean that you are going to be kissing goodbye to both of them. You are still going to need to buy them and add to your pool regularly. It is just not going to be as much as you used to.

It could cost you more money

This may be an issue for some people. There is no denying that buying a pool mineral system is going to be cheaper than chlorine or bromine. However, do bear in mind that since you will need to buy that additional chemical, the costs will start to add up a little. That being said, there are some people who claim that they have actually saved money by having a pool mineral system, so you may fall into the same boat as them. It is probably going to be dependent on your pool, water, and a whole host of other factors.

You will stain your pool

Due to the metals in a pool mineral system, there is a chance that you will end up staining your pool. It is staining that is going to be easy to remove, but do bear in mind that if you let it build up too far, then you are going to have a pool that looks a little bit green. This just means that you need to wash down the sides of your pool on occasion. It isn’t a huge deal, though.


As you can see; there are several reasons as to why you may want to use a pool mineral system. If you do want your water to be a little bit better to swim in, then we seriously suggest that you look at a couple of products that you can use.
