Help keep your aquarium water healthy and your pets and plants thriving with the API Calcium Saltwater Aquarium Test Kit! Testing your water's calcium levels regularly is important because it helps prevent invisible water problems that can be harmful to your underwater buddies. Calcium is one of the most important elements in a reef aquarium. Reef invertebrates such as corals, crustaceans, mollusks and even some types of encrusting algae need calcium to grow and remain healthy. Invertebrates use calcium in aquarium water, which causes calcium levels to drop as over time. This API Calcium Saltwater Aquarium Test Kit measures calcium levels as low as 20mg/L. It contains two calcium test bottles, capped glass test tube and instructions. This kit is specially designed for use in reef aquariums.

Do I need to test calcium parameters in a freshwater aquarium?

No – calcium levels need to be monitored and maintained in reef or marine aquariums, as improper levels can be harmful to corals and crustaceans.

How often should I test my calcium levels?

For best results, test calcium levels with API CALCIUM TEST KIT in your saltwater tank weekly.

    Tool for Reef Tanks

    By Mike on Aug 14, 2021

    Have begun to create a coral reef tank. Corals use the calcium in the tank water. The more corals the more calcium is being used. This test kit is crucial to monitoring calcium levels to know when it’s time to add more. Again I’m impressed with your company professionalism and personal touch. Thank you so much
