Can I convert a chlorine pool to salt water without draining it?

Yes, you can convert a chlorine pool to salt water without draining it. You just add a salt chlorine generator and enough pool salt to get the right level. The system uses electricity to turn dissolved salt into chlorine, so you still get chlorine — it’s just produced on-site instead of adding tablets or liquid. You’ll need a salt cell and control box (around $500–$1,000), hardwire it after the filter, and add about 40–50 bags of pool salt (not table salt).
