The Saltron Retro, from Solaxx, of Delray Beach, Fla., is a chlorine system for aboveground and small in-ground pools that is inserted into the pool itself, not plumbed into existing pipe. The electrolytic process uses less than a teaspoon of salt per gallon to generate free chlorine, which continuously kills bacteria and algae and then reverts back to salt.

The Saltron Retro features commercial-grade titanium cell plates coated with precious metals, a programmable digital timer, clear cell housing and LED indicator lights. Reverse polarity keeps the cell clean and prevents scaling. The switch-mode power supply ensures smooth current to the cell, resulting in a longer lifetime. Critical fault protections are also included, with automatic shut-down.

Preparing a pool for a Saltron system is easy. Simply bring the salt level to 3,000 ppm and begin sanitizing. The Retro is suitable for pools of up to 20,000 gallons.
