To calculate your pool's volume: For rectangular pools, multiply length x width x average depth x 7.5. For circular pools, use (diameter)² x average depth x 5.9. For oval pools, multiply length x width x average depth x 6.7. Always measure in feet for accurate results.
Distribute salt evenly around the pool's perimeter. Brush to help dissolve and prevent staining. Run the pump for 24 hours to circulate. Don't add through skimmers. For best results, add salt when the water is warm and there's no rain forecast.
It's generally safe to swim once the salt has fully dissolved, which typically takes 24 hours. Always test the water chemistry before swimming to ensure proper balance. If the salt hasn't fully dissolved, it might irritate your skin and eyes.
The most effective way to lower salt levels is to partially drain the pool and refill with fresh water. You can also use a reverse osmosis system. Natural dilution from rain can help over time. Regular backwashing slightly reduces salt levels too.
Symptoms include salty-tasting water, eye and skin irritation, corrosion of metal pool equipment, and malfunctioning salt chlorine generator. You might also notice salt residue on pool surfaces or equipment. Always test salt levels regularly to avoid these issues.
Low salt levels primarily affect salt chlorine generators, causing reduced chlorine production. This can lead to algae growth, cloudy water, and potential health risks from inadequate sanitization. The pool might also have a strong chlorine smell, ironically indicating not enough chlorine.
Use salt test strips or a digital salt meter for quick readings. For more accurate results, use a liquid titration test kit. Many modern salt chlorine generators have built-in salt level sensors. Always follow the manufacturer's instructions for the most accurate results.
Pool salt is used in saltwater chlorination systems. The salt chlorinator uses electrolysis to convert dissolved salt (NaCl) into hypochlorous acid (HOCl), which sanitizes the pool. This provides a constant, lower level of chlorine, reducing eye and skin irritation compared to traditional chlorine pools.
The calculator uses the formula: Salt Needed = ((Ideal PPM - Current PPM) x Pool Volume x 8.34) / 1,000,000. PPM stands for parts per million, a measure of concentration. Salinity refers to the salt content in water. The factor 8.34 is the weight of a gallon of water in pounds, used to convert volume to weight.
The ideal salinity range for most saltwater pools is between 2700-3400 ppm (parts per million), with 3200 ppm being optimal for most salt chlorine generators. This range ensures efficient chlorine production while maintaining comfortable swimming conditions and protecting pool equipment from corrosion.
