Why you need Pool Stabilizer for your pool

Chances are, you are going to need cyanuric acid for your swimming pool. This also goes by the name pool stabilizer. Let’s take a closer look at why this chemical is so vital for so many different reasons.

Depending on where you live, as well as the type of swimming pool you own, you are going to need a variety of products for general maintenance. It is obviously important to ensure at all times that your swimming pool is safe to use. You won’t be able to simply leave it alone. A variety of different elements can make your swimming pool unpleasant at best to swim in. At worst, debris, the sun, and other factors can create a situation with your swimming pool that is downright dangerous. Thankfully, it is easy enough to avoid such situations. This is where products and chemicals like a pool stabilizer can prove to be useful.

There are a number of different chemicals available to optimize your swimming pool. There are chemicals that can sanitize the waters. There are also chemicals that provide your swimming pool water with an essential balance. You may also need chemicals to keep algae from appearing, as well as chemicals that control the amount of metal in your water.

Most swimming pools are going to need a pool stabilizer. Let’s discuss the particulars of this chemical, which is also known as a chlorine stabilizer. There are some significant benefits to consider. At the same time, there are also potential drawbacks that you will want to keep in mind.

What Is A Pool Stabilizer?

The whole point of a chlorine stabilizer is pretty simple. We are talking about a chemical that works at stabilizing the chlorine in your swimming pool. If done correctly, the sanitizer will be able to work more efficiently for a longer period of time. In other words, a pool stabilizer will be able to keep the pool cleaner for longer.

That is the basic definition. Obviously, there is a bit more to it than that. It can be helpful to understand what exactly this chemical includes, as well as why it is so important towards helping your chlorine to do its job to its full potential.

Chlorine stabilizer is also known as triazine. This means that it contains not only three atoms of nitrogen, but also three atoms of carbon. Polyeurthane resins are another good example of a triazine. Other examples include different herbicide products and disinfectant products. It is important to keep in mind that cyanuric acid is a precursor to all of those. In other words, no, the chemical you put in your pool to aid your chlorine is not the same as the chemical you use to kill weeds in your backyard.

Some even refer to a stabilizer as a conditioner. Regardless of what you choose to call it, the functions and benefits are going to be pretty much the same. Some prefer to purchase a stabilizer separately. However, it is also possible to purchase CYA mixed in with your chlorine sticks/tablets. This is known as trichlor. It can also be found included with the chlorine shock, which is known as dichlor. The benefit of using such products is that you don’t have to do the measuring yourself. Some prefer to measure themselves, simply to ensure the most accurate mixture possible. The choice is obviously yours to make.

Next, let’s see how you should use your pool stabilizer correctly. The answer can vary, depending on the products you purchase, how often you use the pool and other considerations. The important thing to ultimately keep in mind is that your swimming pool will almost certainly need this chemical.

How To Use A Pool Stabilizer

As we said before, using a pool stabilizer is pretty straightforward. Nonetheless, there are still a few things you will need to do. This is particularly true for those who prefer to measure out the right amount of pool stabilizer themselves.

In terms of how much you should use, you will find the answer varies. In broad terms, make sure your levels do not go above 50ppm. By the same token, you also do not want your levels to go below the point of 30ppm. Going above 50ppm can actually lead to what is known as chlorine lock. This means that while your pool has an ample of amount of chlorine, your readings are going to come up as zero.

Some experts believe your best bet is to maintain sanitizer levels that are roughly 7.5% of the stabilizer. In other words, let’s say your conditioner is at 50ppm. If that is the case, the free chlorine levels should fall to around 3ppm or 4ppm.

Naturally, you will want to read the label of any products you purchase for exact dosage information. As a general rule though, you will want to use approximately four pounds of pool stabilizer per ten thousand gallons of water per every 30ppm. In most situations, you will only need to add the stabilizer at the beginning of the swimming pool season. It is unlikely that you will need to do anything too intensive after that.

In terms of actually adding the stabilizer to your swimming pool, there are a few things to keep in mind. Most of the companies that manufacture this chemical will tell you to add your CYA to a bucket of warm water, before putting the chemical in your pool. Others claim you can simply dump the CYA directly into the water. More likely than not, the product you purchase will leave you with more specific instructions. The benefit of combining it with warm water beforehand is preventing the possibility of irritating the skin of swimmers, or the potential for damage to your pool liner. Don’t forget that we are talking about a type of acid.

Regardless of whether or not you choose to add warm water, you will pour your CYA around the edges of the swimming pool. In the event that your stabilizer is much too high, you have at least a couple of options available to you. There is the possibility of using what is known as a CYA reducer product. Some claim such products do not actually work. We would suggest doing your own research on the matter. You can also dilute your pool by removing a portion of the water currently in your pool, and then replacing that with fresh water. Both options can get messy and frustrating, which is why it is so important to get your levels correct at the very beginning. This is why some prefer to purchase a pool stabilizer that has already been combined with the chlorine tablets.

Finally, make sure you have a stabilizer testing kit. This can tell you in no uncertain terms if your levels are ideal or not.

Let’s break down the pros and cons of a pool stabilizer.
