Here is a page dedicated to Aquarium Rocks. Some are artificial and some are natural, some are intended for freshwater and others saltwater. For freshwater aquariums, there are plenty of natural rocks that you can find lying around that would be great for aquariums! I got the rocks for my freshwater aquarium on a vacation to North Carolina I took! However, if you have a hard time finding some there are plenty of good rocks ready to be delivered to your door for a small price.
For saltwater aquariums, you will likely want some good aragonite rock made by corals. I suggest getting mostly dry aragonite rocks as you only need to seed it with a little bit of “Live” rock and within a year the dry rocks will be covered in beautiful purple coralline algae! Your patience will be handsomely rewarded!!!

This porous characteristic provides a natural biological filter as well as a perfect environment for denitrifying marine bacteria to grow and flourish, which effectively reduces nitrates in your tank.

The Aquaripure filter is a comprehensive biological filter which will completely process all organic matter and remove all nitrates in an Aquarium. The Aquaripure uses beneficial bacteria to break down invisible organic matter and nitrates completely into Nitrogen gas which then escapes into the atmosphere. This same process is even used by some water treatment plants to make wastewater safe for human consumption and to clean polluted water. The Aquaripure does this in an extremely safe and controlled environment and after the water from the Aquaripure is aerated there is nothing left but pure, clean, crystal clear water.
