7 Houseplants That Grow in Aquarium Water (No Soil Needed!)

7 houseplants can grow with their roots directly in aquarium water without using soil. In this video, you will learn how to grow pothos, peace lily, Monstera, Syngonium, heartleaf philodendron, lucky bamboo and spider plants above a freshwater aquarium. These houseplants can help use dissolved nutrients, create additional root cover for shrimp and small fish, and turn an ordinary open-top aquarium into a natural riparium-style display. However, incorrect placement can cause submerged leaves, root rot, restricted water flow and blocked filter equipment. You will see which parts of each plant should remain underwater, how to remove potting soil safely, how to mount plants using hydroponic baskets or filter compartments, and how to control roots before they become a maintenance problem. This method can support a stable aquarium, but it does not replace biological filtration, water testing, sensible stocking or appropriate water changes. Watch before placing a complete houseplant underwater. For most of these plants, only the roots belong inside the aquarium. 12. PRIMARY KEYWORD Houseplants in aquarium water 13.
