AquaLabs KH Minusis a precision-formulated carbonate hardness (KH) reducer. KH Minus permanently neutralises KH, converting excess alkalinity into CO₂ and water. This gives aquarists greater control over water chemistry – allowing them to better meet the needs of soft-water species.
Excessively high KH can restrict nutrient uptake in plants and prevent certain fish/shrimp species from thriving or reproducing. Lowering KH can also improve CO₂ efficiency in planted aquariums, supporting stronger, healthier growth.
DOSAGE DIRECTIONS To reduce KH by 1dKH add 4ml per 30 litres. Do not dose directly on livestock or plants. Always add KH Minus to water. Do not add water to KH Minus. Do not reduce KH by more than 2dKH in 24 hours. Reducing KH will also decrease pH. Scan the QR Code for our online calculator.
