As a pool owner, keeping your pool crystal clear can be very difficult during the hot and humid summer months. While you and your family keep cool, your swimming pool is exposed to grass, leaves, oils, lotions, and much more.
All of these things can take a severe toll on the condition of the water. Luckily, pool service professionals have a long list of quality pool chemicals designed to clean, protect, and maintain your water conditions.
The catch is you must understand what every product is, how to use it, and how much to use for your specific pool size.
In the article below, you will find a great list of the most common pool chemicals every pool owner needs on hand and instructions on making them work for you.
Water sanitizers are some of the most popular and important pool care products on the market today. Pool water can quickly fill with bacteria, viruses, and pathogens that can harm swimmers and keep the algae count low.
While these pool care products are necessary for clean swimming water, they can be strong and even dangerous when not handled carefully and in the right amounts.

For those who have a saltwater pool, your pool salinity level should be near 3,200 ppm. You can use 2 lbs of salt to increase this level to 1000 ppm (for every 10,000 gallons of water).
To Use: Add six bags or pounds of pool salt for every 10,000 gallons of water. This will increase the salinity level of your pool from 0 to 3,200 ppm.
Pool salt instructions (weekly):
- Use 1 lb of pool salt for every 10,000 gallons of water to increase the salinity level by 500 ppm.
- Use 2 lb of pool salt for every 10,000 gallons of water to increase the salinity level by 1,000 ppm.
Bromine is another pool cleaner that doesn't require chlorine. However, since it is not a stabilized product, you cannot use it in an outdoor pool.
To Use: Add bromine to your indoor pool until the sanitizer levels reach 3 – 5 ppm.
Biguanide is a hydrogen peroxide-based cleaner that is a non-chlorinated product. It can be used instead of chlorine.
With that said, it cannot be used with any other swimming pool chemicals listed. To Use: Use biguanide products to get the sanitizer levels to 30 – 50 ppm.

The ideal range for a pool's total alkalinity is 80 – 120 ppm; 1 lb of this product increases the alkalinity levels by 10 ppm for every 10,000 gallons.
pH Increaser or Borax
The pH affects how neutral, corrosive, or scale-forming your water is. Ideal pH levels range from 7.2 to 7.6. Every 6 ounces of sodium carbonate increases your pool water's pH by 0.2 in every 10,000 gallons, acting as a pH balancer.
Calcium Hardness Increaser
Calcium has an impact on how soft or hard your water feels. The best range of calcium hardness is anywhere between 200 to 400 ppm. Every pound of calcium hardness increases the water hardness by 8 ppm for every 10,000 gallons of water.
