In salt water chlorinated pools, the total TDS can be as high as 6000ppm.
• Occasional chemical shock dosing of the pool or spa water should not damage the heater providing
the water is balanced.
• Automatic chemical dosing devices and salt chlorinators are usually more efficient in heated water.
Unless controlled, they can lead to excessive chlorine level which can damage your heater.
• Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical
supplier for the correct levels for your water.
