Re: reverse polarity for a pool chlorinator

i want something that changes the polarity every time the clorinator

a new control box for the salt cell costs around $1400.00.  any help
would be much appreciated,

 thanks.

Seems like those that do the auto-clean function run two banks of cell(s), putting one in 'clean mode' while the other is in 'chlorinate mode'. Assuming you need to clean a cell for the same length of time as long as you use it, and that you need to chlorinate more than half the time the pool is used, you may need two or more cells and wire them via a timer to auto-polarity reverse.
