Stones and pebbles are used to decorate aquariums. These are of different colors, sizes and shapes. Aside from the beauty they provide on the aquarium’s environment, they also give perfect hue that is conducive for living.
I actually just recently added white pebbles to my simple garden pond from recycled tires. Those are just given to me by my aunt since their aquarium fishes died, the reasons I did not asked anymore. Knowing that then, I made sure to disinfect the pebbles before using them. I first washed those with soap and water added with chlorine and zonrox. Then I dried them under the heat of the sun for a day. And a day after, a washed those again with water and soap, dried under the heat of the sun and put them all in our simple garden pond from recycled tires.
