There are many things you must consider before creating the ideal living conditions for the survival of the ecosystem. The most important task you must overcome is the chemical balance of the water and the nutrition you will provide. So, let us focus on foundation elements, calcium, magnesium, and alkalinity.

Foundation Elements

Calcium & Alkalinity

It is best to test the calcium levels every two weeks or better yet, every week. At the same time measure the alkalinity. If the test result shows an increase in calcium, the more likely the alkalinity will drop.

Types of Calcium Products

The cost will vary by quantity and if you prefer to stock up, then get a size that you will have for some time. Here are some calcium products you can choose from to maintain your reef aquarium.
