Fritz Calcium Test Kit – Variable

Product details

Fritz Calcium Test Kit – Variable (04008) is a water testing kit designed to measure calcium (Ca2+) in aquarium water. Calcium is important for maintaining the proper ionic balance in systems where calcium, alkalinity (KH), and magnesium (Mg2+) interact. In saltwater aquariums, regularly checking calcium helps support healthy biological processes and helps you adjust dosing when aquarium demand changes over time. Calcium levels can also be monitored in freshwater systems, where calcium contributes to normal biological functions for plants and supports proper shell and molting conditions for invertebrates.

Features:

• Measures calcium (Ca2+) so you can track changes in aquarium water chemistry
• Supports maintaining ionic balance with alkalinity (KH) and magnesium (Mg2+)
• Helps prevent problems associated with calcium levels that are out of balance in reef systems
• Useful for routine monitoring rather than one-time testing as aquarium demand shifts
• Can be used to guide calcium supplementation in saltwater and (when appropriate) freshwater setups

Specifications:

• Parameter tested: Calcium (Ca2+)
• Tropical community fish calcium guideline: 75+ ppm
• African cichlids calcium guideline: 120+ ppm
• Marine aquarium calcium guideline: 300 to 400 ppm
• Reef aquarium calcium guideline: 400 to 450 ppm
