How to Maintain a Salt Water Pool
A salt water pool still needs regular brushing, skimming, filter care, and water testing. Follow the manual, keep the pump running properly, and fix problems early.

Maintaining a salt water pool
The best way to care for a salt water pool is to put in the same regular maintenance as one would with any other, while also giving some thought to the salt system. While the salt chlorine generator will see to the production of chlorine, it is no substitute for skimming, vacuuming, brushing or tending to the filter and water tests. In short, good maintenance is routine work done to head off expensive problems before they start.
A weekly routine
Most salt water pools are kept in fine shape with a bit of weekly discipline:
- Get on top of leaves and other floating matter before they have a chance to sink.
- Give the walls, ladders, steps and corners a brush to stave off algae and buildup, then vacuum up what has settled.
- Make sure the water level is adequate for the skimmer to function, and empty the basket (with the pump off).
- Take a look at the equipment for any loose parts, warning lights or leaks.
This keeps debris from hampering the filtration and circulation systems and takes the strain off the salt pool hardware.
The salt cell and system
Since the salt cell is what converts the salt to chlorine, it requires some oversight. How you go about cleaning and inspection is dictated by the manufacturer’s manual, but a general approach is to:
1. Note any odd scale on the cell, a drop in chlorine output or warning lights. 2. Verify normal water flow through the system. 3. Service the cell or associated parts as the manual directs. 4. Do not put your own spin on settings or repairs.
Should the system be on the fritz with low chlorine, heavy scaling or constant alarms, leave the troubleshooting to a qualified professional. Homeowners should not be making electrical repairs.
Testing the water
You still have to test the water to keep the chemistry balanced and the pool comfortable. Test strips or a kit will show you the levels for salt, stabilizer, calcium, alkalinity and pH.
Some practical things to remember when handling chemicals: read the label, wear the proper PPE and never mix them. Rely on the numbers, not guesswork. If the readings do not make sense for your particular pool, a pro can put them in perspective.
Filter and circulation
The filter is the heart of the operation so it needs frequent attention and cleaning per the instructions. Backwash if the pressure is higher than usual or after the pool has seen hard use. Be on the lookout for anything out of the ordinary with the pump, such as noise or vibration, or for clogged baskets and cloudy water that comes back after a clean. Neglect the pump or skimmer and you will have circulation issues.
Pitfalls to avoid
It is easy to make the mistake of thinking the salt system does all the work. Other common errors are running the pump when the water is low, forgetting the filter, or letting the skimmer basket get full. And for safety’s sake, turn the pump off before you put your hands in the skimmer or near operating suction.
Time to call in an expert?
If you are dealing with unexplained alarms, signs of a leak, persistent algae or cloudy water that will not clear up with normal upkeep, make a call. The same goes for suspected electrical trouble or if the manual is not enough to sort out the issue. Do not swim in unsafe conditions. A professional can diagnose what is wrong without putting the equipment at risk and save you from costly missteps.
