KENT CICHLID CHEMISTRY 250G Description: Specially formulated mixture of carbonates, sulphates, and chlorides of sodium, magnesium, calcium and potassium with all necessary minor and trace minerals to approximate Rift Lake water chemistry. Designed to provide natural water chemistry to African cichlids and other rift lake fishes without significantly raising pH. Contains no phosphates, nitrates, silicates or organics to pollute the system. Directions: First read the considerations for use section below. Use 1 to 4 teaspoons (6 to 24 grams) of A F Cichlid Chemistry per 10 gallons (38 l) for initial tank setup or for water changes, depending on initial hardness and desired value. Considerations for use: For maximum results, start with water prepared by reverse osmosis. Dechlorinated tap water can also be used. If using tap water, first measure TDS (total dissolved solids) or GH (general hardness). Using this product, adjust the hardness to desired value for the type of fish you are keeping. This is recommended to be 350 to 400 ppm TDS or 12 o to 14 o dGH (Gesamthaerte or German degrees of general hardness) for Tanganyika, 200 ppm TDS or 7o dGH for Malawi, and 150 ppm TDS or 5o dGH for Victoria conditions. A good rule of thumb is 1 to 4 teaspoons (6 to 24 grams) of Cichlid Chemistry per 10 gallons (38 l) for initial tank setup or for water changes, depending on initial hardness and desired value. If possible, use plain R/O water for additions for water lost to evaporation, otherwise use plain dechlorinated tap water. Always mix Cichlid Chemistry outside the tank. Make changes slowly. Important: Measure alkalinity and pH after addition of A F Cichlid Chemistry, then use Kent A F Cichlid Buffer to adjust alkalinity and pH as directed. For best results, add Kent A F Cichlid Rift Lake Trace Elements weekly to replace trace minerals lost to filtration or removed by inhabitants. African Cichlids require frequent water changes, for proper health.
