Maintain the correct calcium level in your marine aquarium with Sera Ca Reagent 3 – 15ml — a replacement testing reagent designed for precise calcium monitoring as part of the Sera calcium test system.
This reagent helps measure the calcium concentration in aquarium water accurately in increments of 20 mg/L (ppm). Regular calcium testing is especially important in marine and reef aquariums, where corals and other calcifying organisms depend on stable calcium levels for healthy skeletal growth and development.
The 15ml reagent provides testing capacity for approximately 7,500 mg (ppm) of calcium. When calcium levels are too low, Sera Marin Component 1 Ca can be added according to the product instructions. When levels are too high, carrying out a partial water change can help restore the correct balance.
