Anacharis is an oxygenating plant that grows beneath the surface of the water with narrow green leaves on long green stems. Sold in bunches. Anacharis helps in algae elimination by competing for the same nutrients that algae needs to thrive, as well as adding oxygen to the water.
The stems can be planted in the substrate or planted in small containers, using sand or a clay planting medium. They can also be anchored with small weights. Anacharis helps to eliminate algae and adds oxygen to the water. You can also plant cuttings from anacharis to multiply the oxygenating benefits.
