Go back to the teacher and find out what he is trying to do, reminding him Calcium Carbonate is insoluble

Re: Calcium carbonate
Should you be using calcium carbonate or calcium chloride, in the past I have made "hard" water - 0.75g MgSO4 and 0.38g CaCl2 to 1 litre of water.

I've used Calgon to soften water. I bought it in the supermarket along time ago.
