I just got my first fish tank for Christmas and I've set it all making sure to wash everything, even the tank, before setting it up and putting the gravel, plants, and features in. I have a filter for my tank and I treated the water as directed and now there seems to be calcium build up appearing on the walls of the tank as well as the filter, heater, and a little house I got to put in. I would greatly appreciate any sort of help to fix this problem
