KH Builder – Adjust KH and pH with Precision

KH Builder is a high-precision preparation designed to safely increase carbonate hardness (KH) and potassium (K) in your aquarium water. It supports stable pH values and is especially useful when using RO water or GH+ only mineralizers. It does not significantly alter GH values and is perfect for planted tanks and shrimp habitats.

Key Benefits:

• ✔️ Increases KH and pH gradually and safely
• ✔️ Also raises potassium concentration (14 mg/l per KH unit)
• ✔️ Helps correct too low pH from RO water systems
• ✔️ Easy to dose, with detailed guidance and calculator

Recommended Dosage:

• 2 ml per 10 L of water increases KH by 1 and potassium by approx. 14 mg/l

Important: Do not dose directly into the tank in concentrated form. Always dilute in 1 L of aquarium water and pour slowly into a high-flow area. Avoid raising KH by more than 0.3–0.5 dKH at a time. Target KH values of 1–1.5 are optimal when used with GH+ Plant.

Why KH Builder?

RO and demineralized water often has very low pH, which can destabilize planted or shrimp tanks. KH Builder solves this by gently increasing KH, stabilizing pH and improving buffering capacity without adding excess minerals.
