Masterline KH Minus aquarium water treatment for plants
Masterline KH Minus is a reliable water treatment solution to lower aquariums' carbonate hardness (KH). By carefully reducing KH, this product helps create soft water conditions ideal for sensitive aquatic plants such as Tonina, Syngonanthus, and Eriocaulon. Lowering KH also leads to a more stable and controlled pH, making it easier to maintain balanced water chemistry in planted tanks.
Every dose of KH Minus generates a small amount of CO2, benefiting plant growth. This makes it a water softener and aids in nutrient absorption and plant health. It is completely safe for fish, shrimp, and other aquarium inhabitants when used correctly.
Dosage and usage instructions
The standard dosage is 1 ml per 10 litres of water, which decreases KH by approximately one degree. To make significant adjustments, repeat the dosage on different days instead of exceeding the daily maximum.
- Do not exceed 2 ml per 10 litres per day, equivalent to a 2-degree KH reduction
- Always dose slowly over 20–30 seconds in areas with strong water flow
- Perform drop-test KH measurements before each dose to ensure accuracy
- Do not use KH Minus to reduce KH below 3 degrees, as this may destabilise the aquarium
Recommendations and precautions
Always follow the guidelines carefully to achieve the best results and maintain a safe aquarium environment.
- Dose away from livestock and plants to prevent direct contact
- Repeat doses gradually for significant KH decreases
- Rinse immediately with plenty of water if the solution comes in contact with the skin
- Store in a cool, dry place away from direct light or frost
- For aquarium use only; never ingest or misuse the product
