The Best Way to Clean a Pool Without Chlorine


Chlorine is one of the most common pool cleaners in the world. It can keep the pool tiles clean and grout-free whilst sanitizing the water and making it safer for everyone who takes a dip.

However, there is a price to pay especially if there is too much chlorine in your pool water. If you are allergic to chlorine or just focused on running a chlorine-free pool, you’ll be better off knowing what happens when you skip chlorine and what your alternatives should do.

What Does Chlorine Do in Your Pool?

Chlorine has four main responsibilities in your swimming pool water:

  • It sanitizes the water
  • It is an algicide
  • It is an oxidizer
  • It can hold residual value in water

Since chlorine is the safest chemical that can meet all these criteria, it is one most comprehensive all-in-one cleaners. Any alternative will have to address these four issues perfectly in order to keep your pool safe and good-looking.

Any stagnant water that isn’t sanitized or oxidized will become a breeding place for risky bacteria and microorganisms. You will no longer have a clear pool that you can enjoy. Instead, your once beautiful pool will turn into a health hazard.

Ozone Pool Purification

This is one of the most effective FDA-endorsed water purification methods. Ozone is a very powerful oxidant that will destroy microorganisms and prevent deposits from accumulating in pipes or on your swimming pool’s tiles.

Since the system uses a UV bulb or corona discharge system to infuse the water with the ozone, there are no chemicals involved hence making the water as natural as possible once you are done with the purification process.

The only problem with ozone is that it has a 20 to 60-minute lifespan depending on pool water temperature. This means that your pool water must be constantly infused with ozone to keep it safe for swimming at all times. This could be a bit costly.

Ultraviolet Pool Sanitizing Light

UV light is a powerful beam that can kill or inactivate any microorganism by denaturing its DNA. The specific UV used in this case would be short wavelength UV (UV-C.) Since UV is also harmful to humans, the cleaning must take place in an enclosed chamber.

This means that the water must be pumped through the sanitization chamber continuously to keep treating it hence creating a healthy swimming pool. The procedure works perfectly regardless of the water temperature and the constant circulation is bound to keep your water healthy and fresh at all times.

Using Plants and Natural Chemicals

Going all-natural and planting plants around and near the pool can absorb carbon dioxide and other contaminating chemicals. Couple this with natural pool products that kill microbes and small organisms and you will have a healthy pool that looks all-natural.

If you want to walk this path, you have to be willing to let go of the convention sparkly white or blue pool and get used to water lilies, reeds, and irises in your pool.

There are alternative ways to keep your swimming pool clean without using chlorine. The best chemical-based alternative would be to use bromine. If you don’t want any chemicals added to your water, you will have to invest in an active system that uses ozone or ultraviolet light to constantly sanitize water before sending it back into your swimming pool. Either way, you will need to work hand in hand with a professional pool maintenance contractor to choose the best option for your pool.
