Main Difference Between Saltwater and Freshwater Pools

Freshwater pools, which most people have in their backyards, use chlorine for cleaning the pools. Saltwater pools do not need chlorine added because they use salt and a process called electrolysis to create their chlorine.

It is important to remember that as water is added to the pool, either through rain or the garden hose, the level of salt in the water will change. Therefore, the levels need to be regularly monitored.

Daily Maintenance

One of the most important things to remember is to clean your pool. This should be done daily with a skimmer to remove debris, like leaves, bugs, etc.

Clean the pump basket & cover daily to eliminate debris that might have gone through the filter and landed there. All this cleaning will help the pool to last longer and the equipment to run better.

Check the water level in your pool daily, as rain and use will increase or decrease the amount of water over time.

The amount of water in the pool will affect other factors such as pH and chlorination, which we will discuss later.

Weekly Maintenance

Check pH level and free chlorine levels weekly. The test kits to do this maintenance are available to buy at your local big box store or can be ordered online.

The normal free chlorine level should be between 1 and 3 ppm. If your chlorine level is above or below those parameters, adjust your generator to get the proper level.

The pH level should be between 7.2 and 7.6. If the level in your pool is too low, you can add baking soda to raise the level. If the level in your pool is high, sodium carbonate can be added to lower it.

It is essential to check these levels. Keeping these levels at the optimal numbers will help ensure that bacteria growth is kept down as well as keep the pool healthy for the family to enjoy.

Monthly Maintenance

Every month, it is necessary to check chemical levels. There are four levels to be checked. They are salinity, alkalinity, stabilizer, and calcium levels. It sounds like a chemistry class, but it shouldn’t intimidate you.

Salinity is the amount of salt in the water. It makes sense to check this level monthly. With a saltwater pool, the salinity changes with the amount of water in the pool.

So, if it rains a few times, that could lower the salinity level in your pool. The ideal level should be between 2700 and 4500. This depends on the size of the pool and the model. Check your owner’s manual for the exact level of your pool.

The alkalinity of your water should be between 80 and 120 ppm. Like the pH level, baking soda can be added to raise it and sodium carbonate can lower it. PH level and alkalinity work together in the pool.

Saltwater pools use a stabilizer to help stop ultraviolet (UV) rays from breaking down the free chlorine. That stabilizer is called cyanuric acid. The level of the stabilizer will depend on the size of your pool, so again, check the owner’s manual.

The calcium hardness of the pool should be between 200-400 ppm. High calcium levels can cause issues with your pool. High levels have caused problems with scaling water lines and burning up salt cells of pools.

If the calcium level is high, the most common and effective way to lower it is to lower the water level or dilute it by adding more water.

Other Maintenance

The salt cell of the pool needs to be inspected every three to six months. This sounds much more difficult than it is. Open the cell and look it over.

If there is scaling in it, then give it a good cleaning. If you see any debris in there, remove it. This simple, quick, and easy step can help you enjoy your pool for a longer time with fewer issues.

Depending on where you live, winterizing your pool may be necessary. If your pool is one that you take down every year and put back up in the summer, winterizing is as easy as draining the pool and giving it a good cleaning before putting it away.

If your pool is a permanent structure and you live in a climate where you experience snow and cold temperatures, follow the below steps to prepare your pool for winter. 

Winterizing a Saltwater Pool

Living in a climate that experiences winter in all its beauty requires preparation for all parts of property maintenance, including that of a saltwater pool.

With proper attention, your pool (or hot tub) will survive the winter months and be there to enjoy in the summer.

First, make sure it’s clean. It seems obvious, but before closing the pool for the season, make sure the water is clean and free of debris.

Check the pump bucket for debris. Make sure everything is ready to be put up for a winter nap.

Second, check your chemical levels and adjust accordingly. You will also want to add anti-staining and winterizing agents. Think of this as adding antifreeze to your car.

When water freezes, it expands. Water lines and other components cannot handle the expansion. This is when you should lower the water level in the pool.

Third, you should winterize the pump, filter, and other equipment. The attention to these intricate details will make all the difference in the summer. 

Finally, cover your pool. Winter is harsh. With storms come debris that you want to keep out of your pool. Also, a cover will prevent any wildlife from attempting to use your pool as their water supply.

Having a cover will also protect you, your family, and any pets from accidentally falling into the pool and getting hurt. 

Should you live in an area that receives heavy snow, be prepared to dig out your above ground pool to keep it from being damaged by the excess weight. 

Benefits of Saltwater vs. Freshwater Pools

If the few extra steps seem like a lot, take a moment to remember the benefits of a saltwater pool. After reviewing them, the minor maintenance differences may not seem as daunting. 

Saltwater pools have a few benefits over freshwater pools. Saltwater pools require little to no chlorine due to the salt. This means there are fewer chemicals in the water, which translates to less money spent. Also, less chlorine means fewer red eyes and less skin irritation. 

Saltwater also has health benefits over freshwater pools. The saltwater helps to exfoliate the skin, making it feel softer. Saltwater pools are also easier on the joints than freshwater due to the bromide found in saltwater. 

Frequently Asked Questions

Read on for some of the most frequently asked questions about maintaining a saltwater pool. 

What maintenance does a saltwater pool need?

A saltwater pool needs the same maintenance as a freshwater pool. A saltwater pool needs a little extra attention in testing the water. Salt levels need to be tested, while freshwater doesn’t. The equipment needs to be checked for salt build-up and scaling. Again, this is a little different than freshwater pools, but should not detract from the overall attractiveness of the saltwater pool.

How often does a saltwater pool need to be serviced?

A saltwater pool does not need professional servicing any more than a freshwater pool does. As with a freshwater pool, if the equipment has malfunctioned and it isn’t something that cleaning will fix, it’s always best to call a professional. However, with proper regular maintenance, a saltwater pool should not need professional attention any more frequently than a freshwater pool would.

Is a Saltwater Pool Less Expensive to Maintain?

A saltwater pool requires fewer chemicals than a freshwater pool. Therefore, most people find it less expensive for a saltwater pool. Pool chemicals are probably the most expensive part of owning a pool, after the initial installation. By reducing the number of chemicals needed, the price of maintaining one is also reduced.

Maintaining a saltwater pool is not more difficult or time-consuming than a freshwater pool. Chlorine has to be added to freshwater pools. Since saltwater pools do not need this additive, there is less money spent. The extra steps of checking for scaling in certain parts of the pool equipment amount to just a few minutes.

There is always the option of hiring a professional pool company to maintain your pool. However, it is much more cost-effective to take a few minutes every day to clean your pool yourself and regularly check all your chemical levels and equipment. It also allows for a little extra time in the summer sunshine.

Following these few easy steps will keep your pool clean all summer. It will also ensure the equipment is working to its highest potential for maximum enjoyment. Taking proper care of it during the off-season will ensure you’ll have the pool for many fun summers. You do not need to be a professional in the pool industry to keep your saltwater pool maintained the right way.
