The thread for flipping shits (and tables)

I don't have litmus paper but could likely obtain some-- my skin's been fine so I don't think it's acidity. My guess is that it's hard water, though I'd have to test it and maybe ask the other housemate on my floor if the shower's been giving him trouble.

If it is, though, I'm not sure what I can do about it. I guess the normal thing is to ask the landlord to fix it? I'm not on the house's lease because I'm subletting, so I don't know if that's like, an option, but I could ask the person who does have the lease.
