I am currently using an 18 gallon Rubbermade / Sterilite container that I bought at Home Depot to store my new water prior to a change. I let this water sit and get it to the right temperature prior to a change. I have been using this container for the past few months. I noticed however that it tends to grow a brown almost algae like film at the bottom. I clean it out with fresh water every few weeks to get rid of the film. For the first time, I let the container dry out completely and noticed a white film on the bottom (I assume it to be salt). I cleaned the container out again. My question is is this container safe? What do you all typically use to store your water.
