EHEIM TORFpellets are natural peat granules designed to soften aquarium water and lower pH levels in freshwater setups. They slowly release humic acids and beneficial trace elements that create a natural blackwater environment ideal for species such as tetras, discus, and other soft-water fish. By helping reduce carbonate hardness and stabilise acidic conditions, these pellets support healthier fish behavior, improved coloration, and more natural breeding environments. Replace periodically to maintain consistent water parameters.
