• Basic water conditioner: Standard when changing water with tap water.
• Multi-purpose purifier: Additional mucosal protection, detox for NH₃/NO₂ (product-dependent).
• Remineralizers: Specifically increase GH/KH
• pH/KH buffer: Controlled acidification or hardening (e.g. for Malawi/Tanganyika cichlids)
• Humic substances & natural additives: Indian almond tree, alder cones, extracts
• Bio-Booster: Faster start-up phase, stable biofilm after filter maintenance
• Water clarifier: Binds suspended particles into larger flakes – for visibly clear water
