Sera pH/KH Minus pH and KH Reducer

Water Parameter Adjustment Immediate reduction of pH and KH values in tropical soft water. Natural processes can lead to a gradual increase in pH. Sera pH/KH Minus immediately reduces pH values and carbonate hardness (KH). KH is adjusted by regulating the pH level. Lowers pH and KH values Creates appropriately soft and slightly acidic water Usage Instructions: To reduce carbonate hardness (KH) by 1°dKH per day, add 5 ml of Sera pH/KH Minus for every 20 liters of aquarium water. Repeat daily dosing until the desired level is achieved. Do not exceed double the dose in one day, as not all animals can tolerate sudden changes in KH of more than 2 degrees. Ensure water is well aerated during dosing. Do not allow KH to drop below 3°dKH (measure with Sera kH test), as this could lead to a sudden drop in pH! Warning! Irritating to skin. Causes severe eye irritation. If medical advice is needed, have product container or label at hand. Keep out of reach of children and pets!
