The 7 Best Solar Pool Ionizers

1. Remington RSI-1000 Solar Chlorine-Free Ionizer – Best Overall

Our top choice for the best solar pool ionizer is the Remington RSI-1000 Solar Chlorine-Free Ionizer. There is no question that this unit has everything you need to reduce chlorine consumption in your pool, and it comes at a very affordable price.

The Remington model is very effective at keeping algae and bacteria out of your pool by merely floating around and using its solar powers. It is estimated that you will use about 80 percent less chlorine when using a solar chlorine-free ionizer.

In addition to spending less money on chlorine, your swimmers will have much less irritation when it comes to eye and skin issues. The solar ionizer is a much more natural way to keep your pool water clean.

We won’t recommend that you stop brushing the edges of your pool, but the Remington significantly reduces the overall maintenance needed to keep your pool looking good. It works on both above-ground and in-ground pools, but you will need more than one unit if you are trying to clean a pool larger than 25,000 gallons. The Remington RSI-1000 also works in saltwater pools; you can just simply adjust your chlorinator not to work quite as hard.

The Remington RSI is not an expensive unit when you consider the cost savings it can provide. Within just a few weeks, you can ultimately pay for the RSI-1000 just in your chlorine savings. This technology may seem new, and solar-powered technology is undoubtedly on the rise, but this particular unit has been around for over 25 years.

2. XtremepowerUS 90120 Pool Solar Ionizer – Best Value

Next on our list is the XtremepowerUS 90120 Pool Solar Ionizer. The XtremepowerUS is the best solar pool ionizer for the money. Unlike our number one choice that will only work on pools 25,000 gallons or less, the XtremepowerUS will work on pools up to 32,000 gallons. That in itself could save you some money, but this unit is still priced cheaper than the number one choice.

This model is an algae killer. It has excellent reviews and does very well to keep the pool bacteria and algae free. The XtremepowerUs works well for shaded and screened-in pools as well as full sun pools. It works best when it is exposed to quite a bit of sunlight throughout the day.

Some people complain that the Xtremepower is too small and does not do enough to keep the pool clean. Mostly this is a highly sought-after model. One thing that all pool owners should remember is that a solar pool ionizer is not going to replace the chlorine in your pool completely. It helps to reduce the amount of chlorine you must add.

3. Floatron SPWP Solar Pool Ionizer – Premium Choice

Next on our list is the Floatron SPWP Solar Powered Pool Ionizer. This is a very efficient model, but it is also going to cost you quite a bit more money. This is a premium choice, and it will cost you about double the price of our best choice.

The Floatron will work in a pool or pond, and it claims about an 80 percent reduction in chlorine usage. If you happen to have a saltwater pool, you can still use the Floatron SPWP; you can just turn down your chlorinator.

This particular ionizer claims to be very durable, but just in case you have any issues, it comes with a 24-month warranty. The Floatron will work in a pool of up to 40,000 gallons. Of all the solar pool ionizers we have reviewed, this one will cover the largest pool.

Even though this is a durable and low-maintenance device, it is recommended that you clean this every three days. The majority of users have had no issues with the Floatron, but some say that it started sinking after about a year. Luckily the warranty should cover the problem if that were to happen.

4. BLUE WORKS Solar Pool Ionizer

Next on our list is the Blue Works Solar Ionizer. This unit is not nearly as expensive as the Floatron, but the quality and durability may be lacking a bit as well. The Blue Works Solar Ionizer works in the same way that the other products we have reviewed will work and claims to reduce chlorine usage by about 80 percent.

The Blue Works comes with two copper anodes as opposed to the one that most of these solar ionizers come with. It is good to have a replacement unit, but hopefully, the copper lasts for quite some time. It will require periodic cleaning, but that is standard for a solar ionizer.

The Blue Works impressively works on pools up to 40,000 gallons. With the inclusion of the extra copper anode, it seems like this unit would land a bit higher on our list. There is no question that this is a good-value solar ionizer. The problem we noticed with it was that it has inconsistent results. For some pools, it seemed to work better than our first choice, and for others, it did not work at all. Trying to narrow down what caused that was a bit cumbersome, but it may be the quality of the copper or the solar panel.

5. Pool Ecologix Solar Pool Ionizer

The Pool Exologix Solar Pool Ionizer is very similar to the Xtremepower US model that is our best value. This model is going to work on pools up to 35,000 gallons.

Pool Ecologix offers some helpful advice about pool size and the effectiveness of the Solar Pool Ionizer. If you have a larger pool, it will take quite some time for the pool ionization process to get started. It may take weeks before you begin to notice the reduction in chlorine, and you will need to clean the copper in the Exologix continually. Cleaning the copper is quite simple, and this unit comes with a cleaning brush to help you do so.

As with many of the solar pool ionizers, this unit has some inconsistent results, and that is why it ends up at number five on our list.

6. Hilltop Solar SN-2A2B Solar Ionizer

The Hilltop Solar SN-2A2B Solar Ionizer comes with the largest copper anode of the ionizers that we have reviewed so far. That may be the reasoning behind its higher price. This Hilltop is quite a bit more expensive than our number one choice, the Remington.

One thing that we like about the Hilltop is an LED ionization indicator. If the unit is working, it will be blue, and the light will be off if it is not working. This is a nice feature to know that your unit is still working to keep your pool clean.

The Hilltop Solar SN-2A2B Solar Ionizer is compatible with inground, above-ground, and saltwater pools and claims a substantial reduction in chlorine usage. The issue we have with the Hilltop is that it only works for pools that are 25,000 gallons or smaller, yet it has a larger copper anode and is priced considerably higher. We can’t quite figure out the math on that one.

7. No More Green Technologies Solar Pool Ionizer

Last on our list is the No More Green Technologies Solar Pool Ionizer. This is a medium-priced unit coming in a little higher than our top choice. The features of the No More Green are about the same as all the other solar pool ionizers that we reviewed. There is one major issue that we have with this ionizer that dropped it to the bottom of our list.

The No More Green is very inconsistent. Although a few people say that is worked wonders for their pool, most had some issues with it. Some of the really bad problems included staining and the unit sinking to the bottom of the pool. It’s important to remember with pool equipment that even though products may look exactly the same, there is a big difference in those companies that use quality parts and those that put together a competing product with the expectations that it will only last a year or two.

Buyer’s Guide – Choosing the Best Solar Pool Ionizer

Now that you have a good base of seven solar pool ionizers to choose from, you must choose one! As you may have noticed from the review, the differences between these units can be quite minimal. We will break down some of the differences for you and give you a quick explanation as to how this product works.

How Does A Solar Pool Ionizer Work?

A solar pool ionizer is not going to use any power outside of the solar power it collects from the sun. This is a simple device with no moving parts. When you purchase a solar pool ionizer, you simply put it in your pool and let the copper do its work. Copper and silver ions will be charged in your swimming pool. When this happens, the ions kill bacteria, algae, and other organisms.

When these things are dead, the chlorine has much less work to do. Therefore, you will go through a lot less chlorine in a year. If you purchase a good unit that works for your pool size, you can quickly recover the cost of the ionizer. Chlorine is very expensive and time-consuming as well. The ionizer will need some cleaning every few days, but it takes a matter of minutes, most people don’t mind the inconvenience for the amount of money saved.

Size

Solar pool ionizers come in a variety of sizes. Most will say directly on the packaging what size pool they would work for. If you look at a unit that works for a pool up to 25,000 gallons, but you have a 30,000-gallon pool, you can add two units. As we often mention with pool equipment, if you have a larger pool but want to try and get away with a smaller unit to keep costs down, you will very likely see little to no results from using the ionizer.

Copper Anode

Depending on what unit you buy, it will usually come with one or two copper anodes. The copper will not hold up forever, you will eventually have to replace this, and you will also have to continually clean and take care of the copper. Most of these all come in about the same size.

LED Light

Some of the solar pool ionizers come with an LED light that will let you know when it is working. This is a nice feature to have, but for the most part, you can assume that it is working if it is in the pool. We don’t recommend spending any extra money on this feature. If the ionizer is in the pool, it should be working.

Warranty

Most of the ionizers that we reviewed had a one or two-year warranty. This is a feature worth getting if you can. These units are exposed to water and sun every single day. If it is not a high-quality unit by the end of the season, you could be seeing some leaks or cracks that will send the solar ionizer towards the bottom of the pool. Having a warranty to go to at this point is an excellent option!

Price

Solar pool ionizers range from $80-$300. The difference in the pricing comes from the size of the pool they can clean and the quality of the parts. Finding a unit somewhere in the middle of this price range should be good quality and capable of killing bacteria in a medium to large size pool.

Conclusion

A solar pool ionizer can be a game-changer when it comes to pool costs. Some pool owners can spend more on chlorine in a month than it costs to buy a solar pool ionizer. Choosing a quality unit that is the correct size for your pool is critical.

The Remington RSI-1000 is our top choice for the best solar pool ionizer because of its ability to clean a 25,000-gallon pool, its fair pricing, and the way it holds up over time. If you want a quality unit that will make a difference in the amount of chlorine you use, this is a great choice.

If budget is your primary concern, then the Xtremepower US is the best solar pool ionizer for the money. This unit will support any type of pool less than 32,000 gallons, although it does seem to work quite a bit better for a smaller pool.
