The LessStress Water Conditioner from Oase actively protects the filter bacteria as well as the sensitive mucous membranes of fish. The vitamin B complex it contains helps to reduce stress in ornamental fish. Less Stress also adds vital iodine to freshwater. Less Stress is available in 100, 250, 500, 1.000 and 5.000 ml containers.


  • Actively protects filter bacteria
  • Reliably renders chlorine and heavy metals harmless in freshwater aquariums
  • Less stress for fish due to special vitamin complexes
  • With vitamin B complex
  • For freshwater


We recommend 25 ml of Less Stress per 100 l of tap water when refilling and changing the water.
