A water softener will cost you way less over the long run, but it's a decent initial investment

Water softener and whole house filter will get rid of all that.

Water softener is a must if you live in hard water areas. You can look up your towns water hardness index with a quick Google search. A water softener is what you are looking for, and if you know basic plumbing you can install one for around $500. It takes salt that you can get from anywhere. It's amazing. It will make the water feel slightly slimy but no more hard water stains, clogged bidets and showerheads will look clean. When you do need to clean all the hard water stains off, use vinegar. You need an acid to get the stains off and this works really well. You can even remove showerheads and dump them into a bucket of it overnight.

Stop putting it in the freezer.

But my schedule is so busy that I simply have to pre boil some then freeze it for meals later…

It all depends on the source/cause of the'hard water'. Ask folks in your area?

Thanks. I've looked into softeners but they are a bit costly where I live and I'm not planning on living here more than a year or two. So looking for sort of short term solution.

Thanks for the advice. What do you think of something like this. I'm not sure if it would work or not.

Haha it's gonna get even more hard. My pipes are gonna be full of sediments.

It's kind of a bore well for housing community. They are planning to switch to city's water which is much better but it's kind of slow process. There's also a castor oil mill nearby, could it be polluting the soil?

I see you're in India! I'm not sure how that product works but the reviews look promising? The hard water softeners I was talking about rely on city water coming into your house under pressure. Not a tank system that needs to be filled. So I really don't know for your case. But as long as it removes calcium and magnesium it'll make the water soft.

The castor should be pretty safe as the heat destroys the toxin in the raw seed.

Try a simple carbon and sediment filter . Think that will be pretty standard. So unless you're in a high farming community or cattle that may taint the ground water - should be good. You can take a sample unfiltered and have it tested for bacteria etc. If there is any, the community should address that as a whole.

Good luck in the shift . I'd still use a carbon and sediment filter on city water. :)
