What I've Learned about Water Properties

So far, i have learned much about water properties. I have learned that water changes density based on its temperature, that water does not conduct electricity, but the minerals in it do, and that solutions make saltwater fish able to survive.I also learned that turbidity is how clear the water is. This will help me on my aquarium because i now know how water acts better than i did when i started.My aquarium models a real ecosystem because it supports fish and has all the things it needs in order to sustain life.
