There is nothing whatsoever to stop you from using what ever in your jugement is a viable alternative pool sanitizing system.
Yes, just install the chlorine generator and add the salt. Your new system will replace the need for residual chlorine.
DOG system!
Ozone is the best choice for an indoor pool. You will still have to have a very small amount of residual chlorine to supplement the ozone system.
A salt system makes chlorine, that's what its there for.
ionisation system stay in water whereas chlorine evaporate into the air, Chlorine irritates the skin, the eyes, and the respiratory system.
Converting to a salt water pool requires the installation of a chlorine generator, and the salt for the pool water. Salt water pool are in fact chlorine pools the difference lays in the fact that chlorine is produced by running salt water through electrodes that in turn releases chlorine from the salt which is usually Sodium chloride (common salt) It may pay to also look at A new more environmentally friendly and healthier alternative By looking at Magnesium and potassium chloride salts.
You first have to convert the pool to a chlorine system As a salt water system is a chlorine system.
The advantage offered by most 'alternatives' is that they, at best, reduce the amount of chlorine you need to add. The only alternative which does the entire job on its own is the Saline (salt) System and although it produces 'chlorine' (from salt dissolved in the pool water) it results in NONE of the obnoxious features attributed to chlorine - no skin irritations, no chlorine odors, no red eyes, no hair damage. A saline pool does not need 'shock' chemicals nor does it require algaecides. Whatever you do, don't get sucked into believing that baquacil is a good alternative.

If you have a salt water pool then you have a chlorine generating system. In a salt water pool through an electric process, the sodium turns into Sodium Hypochlorite. (Chlorine / Bleach ) Now to answer your question: With a chlorine generator system the majority of expense is up front with the unit itself and then when you have to replace the cell. A cell will usually last about 5 years. With chlorine you simply pay for the chlorine as needed. I've had some customers (the Lady's say the salt makes there skin feel smoother. I personally don't notice a difference.
A salt system IS a chlorine system. Chlorine is still the sanitizer. The salt system is there so a chlorine generator can make the chlorine from the salt instead of you having to deal with it. There is no such thing as "best", only tradeoffs. A salt system is expensive even if you break it down per year (with initial and replacement costs). However much less maintenance. A salt system IS perfectly safe for a vinyl, or any type, pool.
