Whether it’s family fun in the summer, or swimming for exercise, everybody loves a splash in the pool from time to time. Unfortunately, due to the chlorine in the water, this isn’t possible for everyone. The hives and skin irritation caused by chlorine can be uncomfortable. However, solar pool ionizers can change the way you swim for good.

There are so many pool ionizers and purifiers in the market that it’s so difficult to search for the right ionizer for your pool. These ionizers come with various features as well as limitations. It’s important to check out the specifications as these ionizers are developed for different pool sizes. We have prepared this brief article to help you choose the right product for your pool.

How Do Solar Pool Ionizers Work?

First of all, what is a solar pool ionizer? They are water purifiers that use solar technology to generate a secure and continuous low voltage trickle feed of solar generated electrical power that ionizes mineral ions into the water of your pool.

Copper, silver and zinc ions have been proven to prevent algae and bacterial growth in water. Although there are different kinds and models of solar pool ionizers (also called mineralizers) they all work according to the same basic principle, that is by dispersing ions in a body of water that contrast and control the aforementioned growth of algae and/or bacteria. You can keep your pool even cleaner with the addition of a solar pool skimmer to remove detritus like leaves and pollen.

The way a solar pool ionizer work is relatively simple. The sun’s rays are harvested and converted into a low voltage current connects to an anode (an electrode that facilitates oxidation reactions). The release of ions and minerals ensures a cleaner pool. Solar pool ionizers require minimal maintenance, though you should strive to keep the solar panel in the ionizer as clean as possible, to maximize its efficiency.

Combined with a range of other solar-powered pool products, like solar pool heaters, solar pool lights, solar pool pumps, and solar covers, your swimming pool can run self-sufficiently whenever the sun is out.

Pros And Cons Of Solar Pool Ionizers

Like any product with a such a specific purpose, solar pool ionizers have both their set of pros and cons.

Pros:

  • Solar pool ionizers are one of the best tools against the proliferation of algae, especially in hotter, humid weathers.
  • Solar pool ionizers use natural minerals with no additives meaning they are a clean and eco-friendly way of contrasting algae and other harmful micro-organisms that infest pools.
  • This also means you need no artificial algaecides and less chlorine (some solar pool ionizers reduce chlorine levels to drinking level purity).
  • The copper-silver ionization is extremely effective in killing harmful bacteria and viruses. Poorly maintained pools have been shown to be a catalyst in the spread of waterborne diseases and infections. The highly efficient anti-viral and anti-bacterial properties of both copper and silver have been known for centuries and can easily eliminate multiple threats such as Legionella, E.Coli and Giardia.
  • While there are other products and methods that reduce algae, bacteria and chlorine requirement in pools (such as UV and Ozone systems), solar pool ionizers are by far the best value when it comes to price and energy consumption.

Cons:

  • Solar pool ionizers do not oxidize or eliminate organic material such as sweat, lotion or makeup.
  • All pool ionizers have a cell that must be replaced after extended usage (in a time period between 3 months and 3 years). These cells can cost upwards of 200$, a figure that must be calculated in your budget but as chlorine, algaecides and PH balancing chemicals are reduced it is still very much a positive investment
  • Some solar pool ionizers have the potential to stain your pool if faulty or not properly maintained. Newer and improved models reduce the chance of this happening drastically.
  • Solar panel products require sunlight in order to function effectively; naturally, sunlight levels fluctuate throughout the year.

Solar Pool Ionizers Buyer’s Guide

Features to keep in mind while buying the right pool ionizer

What is a Solar Pool Ionizer?

Solar pool ionizers are a cost-effective, safer way to make sure your water is clean and algae-free. By placing the ionizer on top of the pool water, the ionizer will collect sunlight to use a charge. Using this charge, it will travel across the water surface releasing minerals and ions into the pool water. This kills off algae and bacteria without having to add chemicals.

Solar pool ionizers are split into the categories of silver ionizers, and copper ionizers. But what is the difference?

Copper Ionizers

Copper Ionizers work as an algaecide. This means that the copper ions kill off microorganisms, bacteria, fungi, and algae. Using a copper electrode that is submerged into the water, a small electrical charge is transmitted into your swimming pool. This releases copper ions which then go on to kill the microorganisms within the water.

Silver Ionizers

Silver Ionizers work as a bacteriostat. This means the silver ions kill off bacteria. However, this happens at a slower pace, meaning chlorine or bromine is still required to ensure your pool is clean. Nevertheless, silver ionizers still act as a more effective cleaner than the Chlorine used in public swimming pools.

Which is the better option?

Although both silver and copper ionizers still require a small form of sanitation such as chlorine or bromine, for the most part, copper ionizers are the most effective way to clean your pool without harmful chemicals overpowering your water. The copper electrode will effectively work as an algae-killer and ensure your water is clean all year round.

What to look out for

  • Copper electrode â€“ although silver ionizers are good for mineralization when combined with chlorine, copper electrodes release the required metal ions into the water whilst using their dc current to kill algae and unwanted microorganisms.
  • Warranty- it is entirely your decision whether you want a warranty included in your purchase, however, I would recommend finding an ionizer with a warranty included in case anything happens to your product.
  • Minimum amount of extra chlorine required- when looking for a solar ionizer you want to ensure you are not having to buy masses of extra chlorine for your water. I would recommend a chlorine reduction of 80-85%
  • Pool size- it is important to ensure the ionizer is able to capacitate to your pool size. Some ionizers can treat 10,000 gallons and others 50,000.

Things to remember

  • Your ionizer will not work straight away- it takes around 24-hours for the copper ions to build up concentration in your pool.
  • Copper levels- remember to regularly monitor the copper levels in your pool. Most ionizers come with copper measuring strips, however, if yours does not, look into purchasing some from places such as amazon. If your pool’s copper levels surpass 0.5ppm, take your ionizer out until the levels drop.
  • Staining- due to the copper ions released, there is a small chance of a copper-colored stain on your pool’s floors and walls.

Final Verdict

XtremepowerUS manufactures the most efficient solar pool ionizer by an impressive margin. With the capacity to nurture 32,000 gallons of water, this ionizer can keep your pool pure, mineralized, and algae-free. It has high built-quality therefore, you don’t have to worry about buying a new one anytime soon. It is one of the highest-rated pool ionizers in the market and has a decent treatment capacity. All in one, it is a complete package for your pool purification.

Frequently Asked Questions

How does the ionizer clean all of my water?

Using the energy collected from the solar panels, the ionizer floats on the surface of the water, moving around your pool releasing metal ions to kill microorganisms and mineralize your pool.


Can you leave the ionizer outside at night?

Yes, your ionizer can stay in your pool 24-hours a day, however, it will be less active at night, and on cloudy days, as it will not be able to collect energy from the sun.


How do I know if it is working?

You should regularly check the copper levels in your water using copper level test strips. If the level of copper surpasses 0.5ppm, take your ionizer out of the water until the levels drop.


Does it need regular cleaning?

Yes, most ionizers come with a cleaning kit. However, if yours doesn’t, it is definitely a purchase you need. The cleaning guide will come with instructions on how to keep your ionizer clean and working.


What is the ideal range of calcium hardness?

The ideal range of calcium hardness is between 200-400 parts per million for swimming pools.
