sera KH/pH-plus liquid KH stabilizer, bottle, 1 pc (aquarium water conditioner)

sera KH/pH-plus liquid KH stabilizer is a ready-to-use aquarium water conditioner supplied in a dispenser bottle designed to adjust and stabilise carbonate hardness (KH) and improve the buffering capacity of aquarium water. The formulation helps maintain consistent KH values and reduces rapid pH fluctuations, supporting a stable chemical environment for freshwater aquaria, including planted tanks and community setups. The product is supplied as a single bottle and is intended for routine water parameter management to promote long-term water stability.

Advantages

sera KH/pH-plus provides a controlled method to increase and stabilise carbonate hardness without adding excessive salts or clouding when used as directed. The liquid format allows precise dosing with the dispenser bottle, enabling gradual adjustments to KH and buffering capacity. Regular use supports more predictable pH behaviour, which benefits biological filtration and the health of fish, invertebrates, and aquatic plants by reducing stress caused by sudden changes in water chemistry.

Suitable for

• Freshwater community aquaria where KH needs to be increased or stabilised
• Planted tanks requiring stable carbonate hardness and pH buffering
• Aquaria with sensitive species that react to rapid pH swings
• Situations after water changes where KH has dropped and buffering is needed

Key specifications

• Form: liquid conditioner in a dispenser bottle
• Function: adjusts and stabilises carbonate hardness and pH buffering capacity
• Application: freshwater aquaria, including planted and community tanks
• Package: single bottle suitable for routine dosing

How to use

Measure aquarium KH and pH before application to determine the required adjustment. Add sera KH/pH-plus gradually to the aquarium water according to the manufacturer dosing instructions printed on the bottle, allowing time between doses to observe changes. Avoid large single-dose additions; introduce the product slowly to achieve the desired KH level and buffering effect while monitoring pH and overall water parameters. When performing water changes, retest KH and top up with the stabiliser as necessary to restore stable conditions.

Usage recommendations

For predictable results, test carbonate hardness and pH regularly and adjust dosing incrementally. Use in combination with good maintenance practices—stable temperature, regular water changes, and proper filtration—to support a balanced aquarium environment. If uncertain about target KH levels for specific species, consult species care guidelines and adjust the product usage accordingly.
