Tetra Pond Water Stabiliser
Tetra Pond Water Stabiliser is used to quickly increase carbonate hardness (KH) in pond water, stabilising the pH value to create safe living conditions for pond inhabitants and combat algae growth.
Tetra Pond WaterStabiliser quickly increases the carbonate hardness (KH) in pond water and therefore stabilises the pH value - to create safe living conditions for all pond inhabitants.
- Combat algae
- Spring
- Summer
- Autumn
- Clear water
- Stabilise water values
- Increase carbonate hardness
Stabilises key water values in garden ponds, helping to create a balanced and stable aquatic environment. This product prevents the water from becoming excessively soft, which can be harmful to pond life. It is particularly effective during all seasons—spring, summer, and autumn—by boosting carbonate hardness to support healthy aquatic ecosystems. Additionally, it works to combat algae growth, which can otherwise quickly overrun a pond and mar its appearance. By maintaining water clarity and quality, it ensures a healthier pond environment, promoting the well-being of fish, plants, and other pond inhabitants. Regular use can also help reduce the need for more intensive water treatment efforts, saving time and effort for pond enthusiasts.
- Increases the carbonate hardness (KH) which prevents the water from becoming too soft
- Thereby stabilises the pH value and prevents fish losses through a sudden drop of acidity
- Stable KH and pH values are basic requirements to make water safe for fish
- Dissolves quickly, does not cloud the water and works immediately
Tetra Pond WaterStabiliser quickly increases carbonate hardness (KH) in pond water to prevent excessive soft water. This effect also stabilises the crucial pH value to prevent potential fish losses through a sudden drop of acidity. The KH level can particularly drop after prolonged spells of rainfall or due to natural decomposition processes. The decomposition of nitrogenous residue such as fish waste, leaves and other organic waste – known as nitrification – releases acids that continuously reduce the carbonate hardness of the pond water. This can quickly put the fish in danger: the lower the KH level, the more the pH value of the water will fluctuate. Tetra Pond WaterStabiliser prevents these problems. Stable KH and pH levels are a fundamental prerequisite for healthy water and the well-being of fish and other ornamental pond inhabitants. At the same time, stable water values are often a prerequisite for the use of other pond care products. Tetra Pond WaterStabiliser keeps KH and pH values stable when using KH reducing products like Tetra Pond AlgoRem to fight algae-growth and medicines like Tetra Pond MediFin. Before using Tetra Pond AlgoRem, you should make sure that the carbonate hardness of the water is at least 6° dH. Tetra Pond WaterStabiliser dissolves quickly and does not cloud the pond water. It is also safe and easy to use and cannot be overdosed. Check your water values regularly with the Tetra Pond Test 7in1. A KH value of 5-10°dH is recommended to stabilise the pH value. Tetra recommends to dispense half a bucket of Tetra Pond WaterStabiliser per 5,000 L of pond water on a monthly basis to increase KH by about 4 °dH. If required re-dose. e.g. after heavy rainfalls or prior to application of biocides, medications or products like Tetra Pond CrystalWater.
