A Complete Guide to Pool Ionizers

Pool ionizers are supplemental disinfecting frameworks that help kills algae and bacteria using copper and silver ions. Sometimes, a pool ionizer is also referred to as a pool mineral sanitizer. 

Typically, pool ionizers use copper and silver particles to fight microorganisms and green growth in the water. Silver particles are more helpful in eliminating microorganisms, while copper particles shoulder a more significant part in preventing green growth. 

Cost of Pool Ionizer

In general, an electric ionizer for an in-ground pool would cost between $700 and $1,500. The cell, which can cost anywhere from $70 to $200 and up, should be replaced at regular intervals like clockwork. Pool ionizers that use sunlight are much more effective, ranging from $100 to $250 or more.

On average, pool ionizers have lower upfront costs and long-term support costs than UV frameworks and ozone generators.

If you purchase an electric pool ionizer, you must consider the costs of having it installed by a professional (you should not attempt to Do-It-Yourself an electric pool ionizer set-up if you are not a circuit repairman or have never done it before).

Do Pool Ionizers Truly Work? 

There is evidence that pool ionizers can effectively kill microscopic organisms and harmful microbes while also preventing green growth.

In any case, one study concluded that when combined with low levels of chlorine, ionizers were more effective at keeping pools clean than higher levels of chlorine alone.

It was also discovered that copper and silver particles have long-term persisting sanitizing power, which keeps the pool more secure even after the chlorine begins to disperse.

How Long Pool Ionizers Last? 

Pool ionizers can last for many years if properly maintained, and the cells are replaced regularly. Most pool ionizer cells can last for a long time but should be replaced when the device wears out.

Professional tip: To ensure your ionizer lasts as long as possible, inspect the parts on a regular basis and clean any scale that accumulates on the cathodes if you have hard water.

Pool Ionizer Issues 

While pool ionizers have their advantages, they may also cause problems for you as a pool owner. The most significant issue you may encounter if you choose a pool ionizer over other disinfecting systems is pool stains. There are also some other issues, including:

·        Pool Stains 

Staining is one of the most common problems that pool owners encounter when using pool ionizers. When the ionizer is arranged incorrectly and delivers many particles for the pool’s volume, the outside of the pool can quickly become stained.

This can also happen if metals are present in the source water. Using a metal sequestering item is probably not a good idea because it can kill the effects of your ionizer. Still, you can use a channel when topping off your pool or topping up off your pool water to limit the presence of extra metals in the pool.

If you notice stains outside your pool, the best thing you can do is act quickly. The longer you leave the stains, the more difficult it will be to remove them.

·        Hard Water 

If you or anybody in your family has problems with hard water, you can add another step to your pool care schedule. That is to clean off any build-up or deposit from the ionizer’s electrodes. Doing this consistently can guarantee that your pool ionizer and the ionizer cell will last longer. 

·        Moderate Acting Ionizers

You’ll have to use a different disinfectant technique with your ionizer as slow or moderate acting ionizer takes several hours or even a day to show effect in the pool and make it usable. Always remember that the bigger the pool, the more water it will hold. And it is directly proportional to the duration of ionization. 

·        Bacterial Opposition 

According to Water Magazine, when copper particles kill microorganisms, a few microscopic organisms can develop resistance. This would significantly reduce the ionizer’s power and require you to use more synthetic compounds in your pool water.

·        Sun-Powered Ionizers Are Inconsistent 

A sun-based pool ionizer will work as long as there is enough daylight to make a difference. If you live in an area with frequently cloudy skies, or if you like to keep a pool cover on your pool when it’s not in use, you should consider an electric ionizer.

How Do Pool Ionizers Guarantee Function? 

Mineral cartridge ionizers and electric pool ionizers are the two most common types of pool ionizers. The fundamental concept is very similar. These devices add copper and other heavy metals to the water on a regular basis.

Electric ionizers use electricity to charge copper or other metal plates, releasing copper or other metal particles into the water. A mineral pack in cartridge ionizers delivers metals.

Some ionizer manufacturers guarantee that no chlorine or leftover sanitizers are used. The main issue here is that a pool that has not been chemically treated can be hazardous for swimmers.

Are Pool Ionizers Safe? 

Even though pool ionizer manufacturers guarantee that their devices consider chemical-free pools, there is no such thing as a safe synthetic-free pool. First and foremost, pool ionizers are not suitable for oxidizing pool water.

Second, copper and other heavy metal pool ionizers are slow-acting, and it takes several hours for the heavy metals to have any effect on microscopic organisms and various microbes.

Pool Staining:

Ionizers in pools add minerals to the water to combat microbes and green growth. They, like anything broken up in the water, can become undissolved and collect on surfaces. If the pool ionizer is left unattended for an extended period, the undissolved minerals will likely stain the pool.

Why Does Staining Occur? 

·        Over Ionization 

Some pool ionizer systems are not managed properly. This could result in ‘over ionization’ of the water, where the release of copper or other minerals is greater than required.

Copper or copper-silver ionization requires only 0.2 – 0.5ppm of copper and 1/10th of silver to work.

Suppose you go to a store, and they tell you that you need to raise the Total Dissolved Solids (TDS) above 500 for the ionizer to work. Then it is almost sure that it is not well regulated, and we would recommend that you find a different product entirely.

·        Mineral Is Not Chelated 

Chelation is an atomic-level holding cycle that aids in keeping chemicals broken up in the water. If the minerals are not adequately chelated, they will cling to surfaces rather than remaining in the water, causing staining.

Current electronic mineral systems detail the mineral cathodes to the point where the minerals are correctly chelated; however, less expensive or more recognized systems may not have this element.

·        Water Out of Equilibrium 

A couple of conditions must be met for minerals to appear from the system. First and foremost, the mineral level must be greater than one section per million (ppm). Second, the pH should be greater than 7.7, and the alkalinity should be greater than 120ppm.

It is critical to test the boundaries of your pool on a regular basis to ensure that everything is in balance. If you have a salt chlorinator, the chlorine release will constantly expand the pH, so it’s especially critical to test regularly and change if necessary.

·        Polluted Source Water 

The water that you fill your pool with may be high in mineral content. You should always test and check your water source before filling your pool with it. High levels of substances like manganese, iron, or copper can cause pool staining. 

·        Debased Salt 

A salt chlorinator converts salt into fluid chlorine in saltwater pools. In any case, some salt isn’t as refined as it should be, so there could be impurities mixed in that break down in the water and cause staining.

Before purchasing pool salt, always check to see if it has been refined, and it is best to look for a good product from a nearby store.

·        Still Need an Oxidizer 

Pool ionizers enable you to reduce the amount of chlorine and other synthetic substances required to maintain spotless, clear water in your pool. In any case, the ionizer alone is insufficient to complete the task.

Minerals are incredibly effective at controlling microbes and green growth while not oxidizing natural matter such as lotions, sweat, and skin cells.

In this case, the ionizer must be used combined with an oxidizer. Chlorine is the most well-known pool oxidizer. Most ionizer manufacturers recommend using less chlorine as an oxidizer (0.5ppm to 1ppm versus 1ppm to 3ppm without an ionizer).

For smaller pools, weekly shock treatment will also take care of the oxidizing needs.

Ozone is a distinctive and effective oxidizer that is introduced into the pool via the pipes. Adding ozone is more efficient than adding chlorine.

Regardless, there is a direct upfront cost, and guidelines in many countries state that you actually need a low chlorine leftover, irrespective of whether you have both an ionizer and ozone. Furthermore, ozone is temporary, does not retain a residual, and is impossible to test for.

·        Not Advisable to Use Stain Remover/Sequestering Items 

Pool stores frequently recommend stain and scale synthetic compounds that remove iron, manganese, and other impurities from the water.

However, you should not use a pool ionizer because it kills the minerals added to combat microbes and green growth.

As a result, you should come up with another method to remove these foreign substances from the water, such as a pre-channel that connects to the hose.

Pool Ionizer Advantages:

  • The water is silky and transparent. 
  • There is no taste or smell of the water from the ionizer. 
  • Particles and minerals don’t dissipate or debase, giving enduring antibacterial force. 
  • You can decrease your pool compound use, which sets aside cash and can eliminate synthetic disturbance like red eyes and bothersome skin. 
  • Particles don’t shape side-effects like chloramines and are not destructive. 
  • Copper wards green growth off. 

Pool Ionizer Disadvantages:

  • Requires additional work to keep up. 
  • It might cause stains on the outside of the pool. 
  • Sun-powered pool ionizers are temperamental in an overcast climate. 
  • Ionizers need hours to get viable and can take more time to function as the pool volume increments. 
  • Test packs that screen pool ionizer execution typically just measure copper. 

Best Pool Ionizer for Use at Home

Xtremepower will solve your algae problem. It is an algae killer and will immediately clean your pool after use. You must inspect the water regularly for any significant changes.

It runs on solar power, and the anode is ionized by solar energy. This removes excess minerals and inhibits microorganism growth.

It is most effective in pools that are screened or shaded. It can effectively handle up to 32,000 gallons of water.

Copper is also known for its excellent antimicrobial properties and has been used in medicine for a long time all over the world.


Pool ionizers, also known as mineralizers in some cases, are based on the rule of adding copper to pool water. When left open for a long enough period of time, ionizers emit significant metals capable of killing microscopic organisms. Nonetheless, pool ionizers have caught the interest of government experts.

A pool ionizer will most likely improve the health of your pool water and assist you in preventing green growth, but it may not be ideal for people who need to avoid pool stains or don’t have the time to treat stains before they become difficult to remove.

It’s not enough to own a pool ionizer, but it also increases your responsibilities of maintenance and care. You need to regularly check for copper or silver and replace mineral packs whenever required. 

However, if you’re looking for a way to reduce your use of pool synthetic chemicals while also making the water milder and gentler on skin, hair, and eyes, an ionizer may be an excellent choice for your pool.
