If conserving water is your priority don't get a salt system. Your draining frequency is sometimes cut in half with swg pools. I know everyone on here loves swg but I have never been a fan so I will be the devils advocate. I have many IC40s that cannot handle a 25k gallon pool and need tab support in the summer. They require a lot of acid, are much more fickle about water chemistry, need to be drained more often, usually from TDS, I have never come across a system that I would call "reliable", and 99% of the time will never pay off in the end (you may get lucky and have a system that lasts forever and some fantastic hookups for salt or free water). On the other hand if you are lazy and don't want to bother with your pool but once a month then they are OK. The amount of time spent cleaning salt cells and adding acid compared to dropping some tabs in a float or feeder has always seemed about a wash to me. I have recommended to several people if they like the feel of salt to just throw a bunch of salt in their pool and save themselves a ton of money (but this will not solve your water concerns).
