Soft water and SWG's

[waterbear]

I have a whole house softener system and a SWG and fill my pool with softened water. I have a fiberglass pool so I run my calcium at about 200 ppm by adding calcium chloride. (Jury is still out whether fiberglass need calcium. I've posted this elsewhere on the forum so I won't go into it here.) I have not noticed my salt level going too high (and my unit does have a high salt shut off). I test my salt level with chemical tests and with Goldline and LaMotte handheld meters. When I have to add water to my pool my salt levels go down from the dilution effects so the amount of salt being added by my softener system is minimal.

EDIT: An advantage of filling with softened water is you will remove or reduce any metals present in your fill water when it runs through the softener. If metals are not an issue and your calcium hardness of your fill water is not too high then there really isn't any advantage to using softened water. If you have metals or extremly high calcium hardness then, IMHO, there are advantages. Just remember to properly balance the water!
