Today we are preparing the water for our habitat! We are going to make brackish water. Well brackish water is a mixture of salt water and fresh water. So first we put some cinder in our habitat. Then we got a rock and put it in the habitat. Next we mixed sea salt and fresh water and we made brackish water. But then we had to check it with a Hydrometer because the water might be to slate.Lastly we put our water in our habitat. Then we put it in the sun.
