Salifert Test Kit Calcium

Product details

Salifert Test Kit Calcium is a laboratory-style aquarium water test kit designed to measure calcium levels in your tank. Calcium is a major constituent of coralline algae and the skeletal material of hard corals, as well as the skeletal needles of soft/leather corals. In closed systems, coral and calcareous growth can deplete calcium over time, so regular testing helps you keep calcium within a stable, target range (rather than allowing large swings).

Features:

• Helps you monitor calcium stability in marine setups by checking for meaningful changes before they disrupt coralline algae and coral growth
• Designed to detect small but significant calcium fluctuations, supporting more consistent conditions rather than “guessing” by dosing
• Test results are read in 5 mg/L increments for practical, step-based tracking of trends
• Has accuracy of 10 mg/L, which is well suited to monitoring changes where large swings (e.g., more than ~15 mg/L) are undesirable
• Not affected by magnesium, so magnesium should not interfere with the calcium reading
• Suitable for marine water, freshwater, and garden pond water use cases

Specifications:

• Measurement step size: 5 mg/L
• Accuracy: 10 mg/L
• Test capacity: Sufficient for 50–100 tests
• Target range guidance: Optimum range commonly referenced as 420–450 mg/L
• Chemical safety note: Ca-1 reagent contains sodium hydroxide and is strongly irritating to skin and eyes; not for consumption; keep out of reach of children
