If you’ve been hauling chlorine buckets from the store every few weeks and spending your weekends testing pool water, there’s a better way. Salt water pool conversions are catching on with homeowners across New Jersey.
The switch costs money upfront, but most families find they’re saving money and time annually on chemicals within the first season.
Here’s what most people don’t realize: saltwater pools still use chlorine. The difference is you’re not buying it by the bucket anymore.
Your pool makes its own chlorine from ordinary salt dissolved in the water. A generator does all the heavy lifting, creating just enough chlorine to keep your water clean and sanitary, with softer-feeling water and less day-to-day attention.
Salt Water Pool Conversion In NJ
How Pool Conversion Actually Works
The conversion itself is pretty straightforward. A technician installs a salt water generator right into your existing plumbing. Inside that generator are titanium anode plates with a special coating. When salt water flows through, those plates split the salt molecules and create chlorine automatically. Your pump keeps everything circulating like it always has.
Before adding salt, your pool water needs to be in good shape. Alkalinity should be between 80 and 120 ppm, calcium hardness around 200 to 400 ppm, and pH sitting at 7.2 to 7.6. Getting these numbers right matters because salt systems don’t do well with unbalanced water. Once everything checks out, several hundred pounds of pool salt are added (pool salt is a cleaner, finer version of salt without damaging residues). Most residential pools need somewhere between 600 to 1000 pounds, though bigger pools obviously need more.
The good news? Your pump, filter, and all the other equipment you already own stay put. The generator cell is installed in line with existing plumbing, the generator power source is a box that is mounted right nearby. The electrical hookup connects to your existing pool power. From start to finish, most conversions are completed in an afternoon.
What You’ll Actually Pay in New Jersey
For a typical 20,000-gallon to 40,000-gallon pool, the cost is approximately $2,900 to $3,900 for the complete conversion. That covers the generator, labor, and initial load of salt.
Generator sizing matters more than you might think. Smaller pools under 15,000 gallons work fine with a 20,000-gallon generator. Mid-size pools between 15,000 and 25,000 gallons need the 30,000-gallon unit. Anything bigger requires a 40,000-gallon system. Different manufacturers offer different sizes, and most technicians will recommend you buy one size up from what the pool technically needs. If the generator is larger, it runs less often to make the same amount of chlorine, which can add three to five years to how long it lasts.
Life Gets Easier After You Convert
Pool maintenance goes from eating up three hours of your weekend to maybe half an hour. The salt generator will give a reading at the unit of the current salt levels, and with greater automation you can get the reading in an app on your phone. You should be checking the reading once a week. The reading should fall between 2,700 and 3,400 ppm. Cells should be cleaned every few months with an appropriate cell cleaner to clean off calcium deposits that build up on those titanium plates.
You still test your water weekly, but the list gets shorter. Instead of checking chlorine every single day, you’re mainly watching pH and alkalinity. Saltwater pools hold a steady pH better than traditional chlorine pools. That’s because the chlorine your generator makes is pure – no stabilizers or buffers like you get in tablets. Your pH creeps up gradually over weeks instead of bouncing around day to day.
Enjoying Your Salt Water System
Most central New Jersey pool owners shut down from October through April. Your generator sits idle during those months, but the salt stays dissolved under your winter cover. Come May, you may have to supplement with some additional new salt; you balance the pH, flip the generator back on, and it starts making chlorine right away. Because the generator is still a salt system, it can be supplemented with chlorine shock at pool openings and closings.
Hometown Pool Supply Co handles service calls throughout Toms River, Jackson, Old Bridge – almost all of central New Jersey. Generator cells eventually wear out after three to five years of use. A replacement cell costs $800 to $1600 installed, depending on brand and how it interacts with its controls. Those titanium plates inside gradually break down from all that electrolysis. You’ll know it’s time for a new cell when your chlorine readings stay low even though salt levels are fine, when you see scaling on the plates that won’t clean off, or when the display starts throwing error codes.
Saltwater pools feel softer on your skin. The water doesn’t bleach out swimsuits or irritate eyes like heavy chlorine does. Your chlorine levels stay consistent all summer without you constantly adjusting chemicals. The conversion costs real money, but once you add up the chemical savings, the time you get back on weekends, and how much better the water feels, most families in Jackson, Old Bridge, and Toms River who make the switch never look back.
