The salt pool chlorine generator system is the way to go. I use to have a hard time keeping up with my pool, dealing with the wife's complaints. Now the pool pretty much cleans itself provided you have enough salt in it (usually 2 bags every 6 months).
I have a blog that is related to the salt chlorine generator system. You can visit it at:

If I can help you with any questions, please email me. Good luck.
