In-line calcium filter?

[GoofyYno]

As I look at my water wall feature and see the calcium build up i wonder is there a in-line calcium filter that would work? I think they have those filters for filling the pool, does anyone know of something that might work?

thanks

There is no avoiding some calcium buildup. You can minimize it by keeping your CSI slightly negative, but never eliminate it completely.
