About this item

  • Not only is it a natural decoration, but it can also filter and purify water
  • Economical and durable: 500g pack meets the needs of small and medium-sized cylinders, can be reused after cleaning, and has high long-term cost-effectiveness.
  • Long term slow-release and long-lasting stability - Coral particles continuously act in the filter tank to prevent water quality fluctuations and reduce the trouble of frequent adjustments, especially suitable for tropical fish such as African cichlids and peacock fish that prefer hard water.
  • Dual purification function - The porous structure of coral promotes the reproduction of beneficial bacteria, assists the filtration system in decomposing fish feces and bait, and physically intercepts impurities to improve water transparency.
  • Convenient to use, flexible adaptation -500g small package suitable for small and medium-sized fish tanks, can be directly placed in the filter box, bottom filter or mesh bag for hanging; Suggest adding 150-200 grams per 50 liters of water, adjusting the amount as needed.


Natural coral filter material for safe water quality regulation - using naturally broken coral to gently increase the pH and GH (total hardness) of freshwater aquariums, providing a stable water quality environment closer to natural habitats for fish.
