Pool chemicals are of great importance to the overall health of your pool. Any pool owner will tell you that the chemicals you use for your pool are the determining factor between a clean and clear pool and a dirty pool. So, pool chemicals are a must-have, but how much will they cost you per month? 

On average, you can expect to pay around $100-$200 a month in pool chemicals; however, there are many determining factors that can alter your monthly cost. 

Monthly Pool Chemical Cost Factors

There is no set price when it comes to your monthly pool chemical cost. The amounts, types, and how often you use these chemicals, all play an important role in determining your costs. 

The Size of Your Pool

It stands to reason that the larger your pool is, the more chemicals you are going to need to use to keep it clean. For example, a 5,000-gallon pool may only require one chlorine tablet. In turn, a 20,000-gallon pool would require four tablets of equal strength. While not all chemicals will require four times the amount in this scenario, you will certainly need more chemicals for the 20,000-gallon pool. 

How Often You Use Your Pool

Another determining factor when it comes to your monthly pool chemical cost is how frequently you use your pool, and at what capacity. If you are a small family and only use your pool on the weekends, you may not need to clean your pool as often as someone who uses it more frequently. A large family or one who hosts large gatherings often should consider cleaning their pool more often. When you use your pool more, you will likely be using more chemicals in order to keep your pool properly cleaned all season long. 

What Kind of Chemicals You Use

Finally, the type of chemicals you use for your pool will play a role in your monthly cost. When it comes to sanitizers, there are several options, including chlorine, bromine, and saltwater. Any of these options are likely to have different costs associated with their purchase. Pay attention to how much of each product you will need and compare that to the cost per use. 

Not only are there different types of pool chemicals, but there are different brands. While some brands may seem like a better deal, it is important to consider the quality of the product. For example, a “value” bucket of sanitizer from a big box retailer may appear to be a good deal, but in reality, the product has been watered down to increase the appearance of value. If you read the instructions, you will likely need to use more of that product in order to achieve the desired result. 

By purchasing quality pool chemicals from a pool builder such as Mastercraft Pool and Spa, you will be using better chemicals. These chemicals will likely come in smaller containers, but don’t let that fool you, these products are more concentrated, meaning you won’t need to use very much of the product each time, therefore making this the more valuable product. 

Where To Buy Pool Chemicals 

When it comes to buying your pool chemicals, it is important to make your purchases from a company that you trust. Pool builders, such as Mastercraft Pool and Spa, are experts in their field, so you can rest assured that they will carry the best brands for pool chemicals.
