One can use winter rains to dilute the pool water or if you winterize the pool then you will be doing a partial drain anyway.
If you use 2 ppm FC per day, then the salt buildup from bleach or chlorinating liquid will be 100 ppm per month so if the TDS number they gave you was accurate, then your TDS was probably higher to begin with.
With Trichlor tabs/pucks, you would buildup 50 ppm salt per month, so half the rate, BUT you would also build up 36 ppm Cyanuric Acid (CYA) per month and that is far worse than salt since it significantly reduces chlorine effectiveness unless you proportionately raise the FC level. So you can end up getting algae growth, cloudy water, and other problems. ALL forms of chlorine end up increasing salt levels because when the chlorine is used/consumed it becomes chloride (salt). As others have noted, salt is the least innocuous side effect from chlorine. Increasing CYA is much worse.
With Cal-Hypo, the salt buildup is in between that of Trichlor and bleach or chlorinating liquid, BUT you would also build up at least 42 ppm Calcium Hardness (CH) which is OK if you have a vinyl pool where you start with low CH from tap water, but would not be good in a plaster pool or other pool already saturated with calcium carbonate to protect plaster surfaces (i.e. where the CH was already high enough).
