How to grow vallisneria

Vallisneria makes a fast background curtain of ribbon leaves that bend along the surface. It grows in low to medium light without CO₂ and spreads by runners. It likes hard water, which suits livebearers and many cichlid tanks.

Common problems

  • It melts with liquid carbon products (glutaraldehyde); avoid them in a val tank.
  • Leaves shading the tank: cut long leaves at the base, not halfway.
