Water Softening: Peat Granules are recommended for fish that prefer soft, acidic water (i.e. Amazonian cichlids, discus, angelfish). They soften aquarium water naturally and help achieve pH levels that are needed for breeding certain tropical species. Ideal Environment: These granules contain humic acid, tanning agents and trace elements that are essential for various life processes. Each granule is highly concentrated for maximum effectiveness. Usage: This filter media is suitable for freshwater. Ideal for use with most canister filters; for best results, replace every 4 weeks. Pack Includes: 500g (17.6 oz.) of peat granules for your aquarium filter.
