About this product
★Water purification and water quality adjustment (effective for neutralizing the pH of oxidized aquarium water). For both saltwater and freshwater.
★Disinfected. Can be used immediately after a light rinse.
★Oyster shells will not excessively raise the pH. The fine cavities in the oyster shells provide a habitat for beneficial bacteria to multiply. They also serve as shelters for small fish and shrimp.
★When the water becomes acidic, the oyster shells dissolve, maintaining a neutral to slightly alkaline pH.
★Crushed farmed edible oysters from Hiroshima Prefecture.
