Wow I just learned of Hard Water vs Soft Water. I googled and yeah its a moderately hard Water area. So I assume this is normal (or at least nothing to be alarmed about)?

Yup, completely normal. I have hard water and my kettles get calcium buildup after a handful of uses. Soak with white vinegar to remove the buildup. Or if you're like me and forget until last second, boil 50/50 vinegar/water and deal with the vinegar smell, lol.

Ahh thank you! Kinda freaked out seeing so much weird stuff on the water's surface. Out of curiosity would regular consumption of such water have any adverse effects?

Hard water is fine.

I'm guessing your UK, but in America it's a lot worse and most people need salt exchangers.

Just think of it as "mineral water".

But I think other people talking about residual fat are probably right. If you have hard water, you'll notice a white chalky substance on faucets and stuff, or if you leave a glass of water out to evaporate, it'll leave behind the minerals.

I'm from Singapore, and fortunately the tap water is clean enough that I basically drink straight from the tap.

Damn that's an experiment I'll be trying for my stay here! Pretty cool to learn about these stuff

Hard water is still safe to drink.

The issue is it leaves residue in pipes, on faucets, and the biggest issue is inside hot water heaters because it hurts efficiency.

If you're renting you've got zero to worry about.

If you want to get rid of accumulation on dishes/faucets just wipe it down with vinegar and that breaks it down

Very good to know! Just trying to avoid potential stomach upsets while overseas. I'll be gone in a week or so, so not concerned about the other stuff :P
