It is easy to practice proper pool chemistry. This guide will teach you everything you need to keep your pool clean.

Water Balance

The pool water must be balanced. It shouldn’t be too rough or too soft.

Balancing your pool involves keeping the pH between 7.4 – 7.6, which is slightly higher than neutral on the pH scale.

This balance can be maintained by using 3 ingredients:

  • pH levels
  • Levels of alkalinity
  • Levels of calcium hardness

pH Levels

The ideal pH level ranges between 7.4 and 7.6

The pH level is not enough to make it stable. The pH level can be affected by rainwater, swimmers, or any other substance that gets into the water. If pH is low, your water is acidic. When pH is high, it is basic.

Our tears are pH neutral to give you an idea about pH. It would burn if it had a low pH. It would also dry out our eyes if it had a high pH.

Keep a supply of pH Enhancer on hand as pH levels change often. If you have pH balance issues, we recommend monitoring your Alkalinity levels. Alkalinity increasers can also be added to your pool to raise its pH level. Talk about killing two birds with one stone.

Alkalinity levels

The Ideal Alkalinity Level is between 100 pm and 150 ppm.

Alkalinity acts as a pH buffer. It absorbs major water changes before they affect the pH.

The good idea is to have a large supply of Alkalinity boosters, as alkaline levels can change quite quickly.

Calcium hardness

The ideal calcium hardness level ranges between 175 ppm and 300 ppm.

Your water will be hungry for calcium if it isn’t. It will eat plaster from your pool and anything else that it can find. This is what calcification is on your pool’s floor and walls.

Your pool walls and equipment will be protected if you add calcium hardness. Too much calcium can lead to scaling and other problems.

How to keep your water balanced.

You should monitor your pH and alkalinity levels at least once per week using a home testing kit or test strips.

These chemicals are essential to maintain a balanced pool.

  • pH Booster
  • pH Reducer (hydrochloric Acid)
  • Alkalinity Booster

Notice that I didn’t mention alkalinity reducer. Here are the reasons that most major pool chemical companies don’t produce it:

  • Alkalinity enhancers will increase pH and alkalinity if they are low. If your pH is below 7.4, you may need to add some pH enhancers. This can be used for fine-tuning instruments.
  • A pH decrease can lower pH and alkalinity if they are high.
  • You can use a pH reducer if your pH is too high.

Your pool will work better if it is balanced at all times.

Sanitization

Chlor is the most popular pool sanitiser, but you can also use other forms, such as:

  • Salt
  • Stabilized Chlorine
  • Minerals

Chlorine Levels

The Ideal Chlorine Levels range from 1 ppm up to 3 ppm.

The cost-effective and highly effective way to kill bacteria and algae is with chlorine

There are several ways to add chlorine to your pool water.

  • Tablets containing chlorine
  • Chlorine powdered or granular chlorine
  • Salt Generator: turns regular table salt into chlorine

Chlorine Alternative – Sparkle Purifier

This is an alternative to chlorine. This is an effective pool sanitiser and makes the water feel softer.

These packages contain more than conventional chlorine-compatible chemicals and are typically more expensive. They can be purchased in powder/granular or tablet forms.

Mineral System

The ideal level of chlorine for use in a mineral system is 0.5ppm

A mineral system, which resembles a chlorineizer, introduces silver and copper minerals to the water. Although these minerals are faster than chlorine, they can sanitize water.

Mineral systems are not a complete alternative to chlorine. However, they can be used as a backup.

What is Pool Shock?

Chloramine or chlorine is formed when a chlorine particle attacks or kills bacteria or organic material in water. This particle floats in water until it can be oxidized or broken down.

What is Breakpoint Oxidation?

Breakpoint oxidation can only be achieved if the chlorine reading is 10 ppm higher than your combined chlorine reading.

There are two types of chlorine readings: combined chlorine (CC) or free chlorine (FC). The chlorine that is available and free of charge to kill is called free chlorine.

Note:┬áSome pool shock products contain unstabilized chlorine or none at all. They will work hard and quickly get absorbed by the sun’s ultraviolet rays. It is important to shock the pool at night or dusk and leave it running for 8 hours.

Other types of pool chemicals

You could maintain a healthy pool year-round if you used pH, alkalinity, calcium, and sanitisers. There are some other products that you should know about if you ever need them.

Cyanuric Acid and Stabilizer

Stabilized chlorine is what most chlorine products are. If you start with freshwater, you may add cyanuric Acid (aka water stabilizer) as a stabilizer base. This will ensure that the sun’s ultraviolet rays don’t quickly oxidize chlorine. This chemical will protect your chlorine against the sun.

Cyanuric Acid Reducer

Sometimes your levels of cyanuric Acid will rise above what they should be. This can lead to serious health problems. There are many ways to reduce your cyanuric acids. They don’t naturally go down, but there is always a Cyanuric Acid reducer to help you eliminate this problem.

Algaecide

Algaecide acts as an alga preventative. Although some algaecides claim to kill algae on the market, the best is chlorine.

As a backup, use an algaecide. The algaecide can be used to keep the algae at bay while you wait for the chlorine to return.

Algicide may not be the best choice if you have an algae problem in your swimming pool. We have a solution that will eliminate the algae and prevent it from returning. Click the button to access our guide on how you can get rid of algae permanently.

Clarifier and Floc

A water clarifyer removes all the tiny particles from your water and makes it more clear.

Flocculant or Flocculant grabs the tiny particles and brings them together to sink them to the bottom. You will need to vacuum the water to remove pool floc particles.

Removes scale and stain

You can use a water remover, such as stain or scale remover, to remove any metals from your water.

Metals can stick to your pool walls and cause unsightly stains if exposed to the solution.

The Nutshell…

You need to maintain a healthy and safe swimming pool by keeping your chemicals at the following levels.

  • pH: 7.4 to 7.6
  • Alkalinity: 100-150 ppm
  • Calcium Hardness: 175 – 225 ppm, 225 – 275 ppm plaster pools
  • Salt Water Pools: 1 – 3 ppm (I recommend keeping it at 3ppm).
  • Bromine pools: 3 to 5ppm
  • Biguanide Pools: 30-50 ppm
  • Mineral System Pools: 0.5ppm chlorine

You should ensure good pool circulation and filtering. Also, make sure you vacuum and skim your pool regularly.
