Salt Water Chlorinator and Salt Cells are the two main components in sanitising your pool. The Salt Water Chlorinator sits on the wall where you can set your output and timers, which is then connected to your Salt Cell via an output lead. The Salt cell is plumbed within the pipe work, as water passes through the housing and a small amperage current passes through the cell plates, which is where the oxidization happens and small chlorine gas is produced and returning to the pool, effectively sanitising your pool
