Salifert Test Kit KH/Alkalinity

Product details

Salifert Test Kit KH/Alkalinity is a Profi-Test kit designed to measure carbonate hardness (alkalinity), an important parameter for maintaining buffering capacity and supporting stable pH in aquariums and ponds. In marine systems, alkalinity reflects the total carbonate and bicarbonate available to help stabilize pH and support the formation of calcareous material in coral and other carbonate-using organisms. Practically, this kit helps you check whether your alkalinity is holding steady (or drifting) so you can make informed adjustments rather than reacting to symptoms.

Features:

• Measures total carbonate and bicarbonate levels, commonly referred to as alkalinity or carbonate hardness
• Helps support pH stability by tracking buffering capacity in the aquarium/pond
• Sensitive test with small resolution and a sharp color change to detect subtle KH changes
• Designed to be suitable for marine water, freshwater, and garden pond water testing
• Includes buffer additive intended to help correct alkalinity without upsetting system pH
• Covers a testing range suitable for regular monitoring, with sufficient reagent for many tests

Specifications:

• Test sensitivity: Detects small alkalinity changes in steps of 0.1 meq/L
• Recommended stability guideline: Aim for alkalinity around 2.8 meq/L with no more than ~5% fluctuation (about 0.14 meq/L)
• Test capacity: Sufficient for 100 to 200 tests
• Included correction support: Salifert KH + pH buffer additive for simpler alkalinity correction without upsetting pH
• Water types: Marine water, freshwater, and garden pond water
• Safety note: KH/Alkalinity reagent contains a dye; avoid spills on fabric/materials, keep out of reach of children, and do not consume
