Salt water swimming pools: The basics

Saltwater pool owners across the globe will tell you that this type of pool is far better than the average chlorine swimming pool (which we will go into more detail with later on).

For now, let’s focus on the basic rules to successfully maintain a salt water swimming pool all year round.

Sanitation

Keeping your pool free from dirt and debris is essential for ensuring the water is clean and safe to swim in. While chlorine plays a big part in destroying some bacteria, salt water pool owners also have a role to play.

Showering before entering the pool will reduce the build up of bacteria, and it goes without saying that you should stay away from the pool water if you are unwell.

Water pH balance

If your pool’s pH level is between 7.2 and 7.6 then you’re doing it right. This not only helps with pool sanitation, but it is also vital for protecting skin and eyes from irritation. When your pH level is in range, the water is nice and clear. If it starts to look murky or cloudy, the pH levels should be the first on your list to check.

Pool circulation

A working pool pump and pool filter are essential during the summer when they will be in use from 8 to 12 hours a day. The circulation system is used to disperse chemicals evenly throughout the pool water and filter any dirt and debris to waste.

Regular pool inspection

During the summer, you should inspect your pool on a daily basis. Looking for cracks, leaks and any other damage is important if you want to avoid parting with your hard-earned cash. Checking water levels and regularly vacuuming your pool are all part and parcel of the job.

How to maintain a saltwater pool : A step by step guide

Salt water pool maintenance for beginners is not that onerous.

Salt water pools are pretty easy to maintain if you consistently check over them. You will need to perform some tasks on a daily basis, whereas others may only need to be done every few weeks or even months.

Step 1: Regularly clean filter, pump and skimmers

The pool’s filtration is extremely important. If damaged, this could lead to a pool closure until it can be fixed. To ensure this doesn’t happen, you should check the skimmer basket and pump strainer basket several times a week. Leaves, bugs, dirt and other debris that get through these baskets can clog the filter which will leave the pool water cloudy and dirty.

A pool skimming net is a great tool for manually picking out larger pieces of debris. For smaller pieces, a pool vacuum is recommended. Robotic and automatic pool vacuums are handy if you don’t really have the time to do it yourself.

Step 2: Clean the salt cell

A salt cell produces the chlorine in saltwater pools as opposed to manually adding it. Over time, calcium and other minerals tend to build up on the inside plates, in which case they need to be cleaned. So how do you clean a salt cell? Let’s take a look.

  1. Begin by removing the cell and manually picking out any build up you can see with your hands.
  2. Use your garden hose to wash the cell out for any parts you may have missed.
  3. Now it’s time to soak the cell in a muriatic acid solution. We would recommend purchasing a pre-mixed solution from your local pool supply store as handling acid can be a dangerous job.
  4. Soak the salt cell in the solution for 15 minutes before placing it back in the plumbing system.

Step 3: Maintain surrounding areas

As well as keeping the pool floor and tiles clean, the deck around the pool will collect a build up of salt over time. At least once a week, you should hose down the area and push the water back into the pool with a soft brush.

Step 4: Keep an eye on your pool’s water chemistry

Testing your water levels is vital when it comes to maintaining the pool water. This should be done every couple of days during the summer months and every couple of weeks throughout the winter.

Don’t hesitate to ask for advice from professionals at your local pool supply store as they will always be more than happy to help.

Saltwater pool checks

We have put together a short list of saltwater pool maintenance tasks that should be completed every day, week or month. It may seem like a lot, but taking 5 minutes out of your day to check things over is nothing in the long run.

Every day

During times when the pool is used the most, you will probably find yourself having to clear out debris every day with your skimmer net. This is also a good time to check the skimmer and clear out the basket.

Every week

The pool will need to be vacuumed at least once a week, twice if used every day. For this, we recommend purchasing a robotic vacuum so that you can free up some of your time (the most popular is the Dolphin Nautilus CC Plus).

You should also look to rinse the filter, pump and skimmer down with a hose.

You will need to test the pH levels and free chlorine level using test strips, or you can purchase a digital water quality meter that may be more accurate.

Salt water pools generate chlorine using a salt chlorine generator (see diagram of a CircuPool CORE35 Salt Chlorinator System), so there is no need to manually add this chemical, instead you just add pool salt to the salt water cell.

Once a month

Salt water levels should be checked over at least once a month. To do this, you can use saltwater test strips or a Digital Salinity Tester for Salt Water. If salt levels need to increase, simply add more salt to the salt system.

Salinity levels should be between 3000-3500ppm but check the manufacturer’s instructions just to be sure.

Here are a couple of other levels you should also keep an eye on:

Calcium hardness

Too little or too much calcium can cause cloudy water and damage to pool walls and other equipment. Anything between 200-400ppm is looking good.

Stabilizer

Chlorine levels deplete over time, particularly in outdoor pools. In theory, stabilizers act as an SPF to chlorine. These levels should sit at around 70-80 ppm and if they are too high, adding fresh water is recommended. If too low, you will need to add cyanuric acid.

Once every three months

Check the salt cell for any build-up and clean it up as required.

Saltwater pool vs regular chlorine pool: The difference

The difference between salt water and chlorine pools
There is no visual difference between the two

Saltwater pools and traditional chlorine pools are not too dissimilar to one another. Both include water and chlorine, so what’s the difference between the two?

Saltwater pool

Before we get into it, we want you to know that saltwater pools are not filled with salty water although salt is added to the water on a low scale.

Saltwater pools generate their own chlorine as opposed to chlorine pools where it is added manually. This is probably the biggest difference between the two as saltwater pools require less chemicals and attention.

Although the self-generating of chlorine may sound appealing, this does come at a cost and seeking professional help adds to this.

Chlorine pool

Installing a chlorine pool is less expensive, but they do require more maintenance. Balancing chlorine levels can often be a nightmare if you add too much or not enough.

However, chlorine pools do not require as much electricity and are also easier to fix by yourself rather than by contacting a professional.

Pool Maintenance Course

When I first bought my house with a swimming pool, I knew nothing about cleaning and maintaining it. I was recommended Swim University’s Pool Care Handbook and video course so I bought it and have never regretted it.

It was probably the best money I spent that year as I have saved thousands by doing it myself.

Salt Water Pool FAQs

How much does it cost to maintain a saltwater pool?

The upfront costs for a saltwater pool are certainly higher than for a similar traditional chlorine pool. The salt cell generator alone can cost between $1000-$2500 to install.

However the ongoing costs can be lower. When we look at the cost of adding chemicals to a saltwater pool, this may be around $100 a year as opposed to perhaps $800-$1000 for a chlorine pool.

Chemicals aren’t the only cost though as saltwater pools require a lot more electricity they are much more complex than chlorine pools. This is where it can become expensive if you need to seek professional help.

Can you use pool shock in a saltwater pool?

Yes, it is perfectly okay to use pool shock in saltwater pools. Although the system has a ‘super chlorinate’ option, there is nothing wrong with adding a little pool shock to clean up cloudy water. Using this product will not affect the pool in any way either.

We recommend shocking your pool regularly during the summer and every now and again during the colder months to keep algae and other bacteria at bay.

How do I winterize the salt chlorinator?

This is a great question as it is unlikely that your saltwater pool warranty will cover freeze damage. To winterize the salt chlorine generator, you will firstly need to drain every last drop of water from the entire manifold assembly including the cell and the tri-sensor. You may even be able to remove the cell completely if your manufacturer recommends it.

If you do remove it altogether, remember to cap the check valve connections to prevent water from entering.

Does salt water pool taste salty?

It is a common misconception that salt water pools will taste salty, like sea water. But this is not the case. Although salt is added, it is put into a salt water chlorinator which then converts the sodium chloride (salt) into chlorine before it enters the pool.

The salt level in sea water is around 35,000 ppm (part per million), human tears are around 9,000 ppm but a salt water pool is normally only around 3,000 ppm.
