Micon, welcome to the forum! Operating a pool with the SWCG (salt water chlorine generator) isn't very different from a non SWCG pool. You do need to look after the salt level, but only after water is added to the pool (the salt only leaves the pool by backwashing and splashout). It's strongly recommended to keep a close eye on your pH, many swcg pools experience an upward creep, which requires regular additions of acid to correct (however, many pools never see this creep). The manufacturers recommend cya of 60 -80 ppm, do some research - it's your pool and your choice. You will probably want to read through the SWG and auto chlorinator section of the forum, there are some real experts that frequent there and have awesome advice to give.
In short, it's not too different from using more traditional chlorinating methods, you are just cutting out the middleman by generating your own chlorine.
Some folks say not to add the salt for 2 weeks after the plaster is applied, though others say that you can add it immediatly, I'd play it safe and wait the 2 weeks to protect your investment - you can get a 'floater' ( $10 or less) and use trichlor pucks until the salt system is ready to fire up, it adds chlorine and cya and will keep the pH down while the plaster cures.
On behalf of the nice folks here, I wish you well with your new pool and hope that you will use this forum to make your pool ownership experience as easy and hastle free as possible. Again, welcome! - Waste
