Aquatic Science
KH + 5kg - Aquatic Science
€57,99
KH+ 5 kg – Aquatic Science
Stabilise the carbonate hardness for an optimal water balance and healthy pond inhabitants.
Aquatic Science KH+ 5 kg increases the carbonate hardness (KH) of the pond water while providing essential trace elements. A stable KH value (between 6 and 12°dH) is crucial for maintaining a constant pH and a well-functioning biological balance. Rainwater often lowers the KH, which can disrupt filtration, plant growth, and fish health.
Key benefits
-
Increases and stabilizes the KH value – prevents pH fluctuations.
-
Supports biological filtration – optimizes the performance of beneficial bacteria.
-
Promotes healthy plants and fish – prevents stress and stunted growth.
-
Rich in trace elements – contributes to a vital and stable ecosystem.
-
Large 5 kg package – ideal for the regular maintenance of medium to large ponds.
Application
-
Spread the product evenly over the water surface (do not dilute beforehand).
-
Work in small quantities and wait at least 24 hours between two treatments.
-
Check both the KH and pH values after each application.
-
Recommended KH value: between 6 and 12°dH.
-
Store in a dry place between 10 °C and 25 °C.
