Read About Choosing Calcium Reactors

To maintain good calcium and alkaline levels in your tank, add a calcium reactor, especially to those containing lots of reefs.

Things to Consider:

Initial setup -- While the initial setup of a calcium reactor can seem like a bit of an investment, it is virtually maintenance-free afterwards and well worth the cost.

Less expensive -- For less expensive solutions, there are liquid product available that can be added to the water to increase calcium levels.
