You can put stones and aquatic plants without affecting the beauty of your tank. However, there are two points to note. It can be paved with 3~5 cm of bottom sand, which is beneficial to the growth of aquatic plants and looks natural all day. In addition to your big filter, it is suggested to add a small submersible pump to blow at the bottom, and then let the fish manure be sucked away by the high-power filtering facilities, otherwise it will get stuck in rocks, aquatic plants and sand, causing pollution.
