How to Keep Moss in Aquariums

Many aquarists prefer to use live plants in their aquariums. Live plants provide a very natural look, but can be difficult to maintain. Designing a planted aquarium is mainly a matter of preference, but a good number of people prefer to start with a base of moss to give their tanks a ̶0;carpeted̶1; look. There are a few different types of moss to choose from. The easiest to establish is Java Moss, which can be found online or at the local aquarium store.

Instructions

    • 1

      Rinse your gravel. Add it to your tank to create a substrate layer 2 to 3 inches thick. Add water and use the water conditioner as directed.

    • 2

      Take a small handful of moss and secure it to a rock using the thread. Use your finger to poke a shallow hole in the tank̵7;s substrate. Place the rock in the substrate and lightly cover it. Repeat this process two or three times in different areas around the tank.

    • 3

      Install a filter and powerhead to the tank to create a strong flow of water around the moss.

    • 4

      Allow the moss to take root in the gravel. Use the plant fertilizer as directed for the first two or three weeks to encourage growth. Add goldfish or other small fish to provide natural nutrients.

      Trim the moss as it grows to create a ̶0;carpet̶1; look in your tank.
