Black, Medium Particle (~5mm) Fired Volcanic Ash Base Substrate


  • Natural volcanic ash with beneficial properties for aquatic plant growth and long-term 
    care of fishes and motile invertebrates requiring slightly-acidic, low-GH water conditions.
  • Ideal for use as a substrate in shrimp biotope aquaria.
  • Binds elements that contribute to hardness, lowering GH and resulting in a slight 
    acidification of alkaline water to a pH of less than 7.
  • Used as a primary substrate, forms the basis of a stable growth medium for rooted 
    aquatic plants by: 
    1. Permitting development of strong root systems.
    2. Encouraging nutrient-uptake through roots via increased interstitial water circulation
    (relative to higher-density substrata) and acidic pH environment.
    3. Allowing roots to remain sufficiently oxygenated to maintain plant health.
