Hard water help

I've used this for years when draining my tub. It's the best. Now I'm having a hard time finding it

Works great for hard water

Our local water is very hard and this allows us to get it back into a normal range in our tub. This does need to stay in the tub for at least 4 hours for us, even though directions say 2-4 hours. Then you rinse off the filters and you're good to go. We just do it when we change water.
