Calcium Reactors, & Aquarium Kalkwasser

Aquarium Calcium is a major building component for the skeletal systems of most invertebrates, therefore it is vital to the health of a successful reef aquarium. This element can be a hassle to dose slowly enough for proper dissolution, not to mention replenishing it promptly when depleted, and to the appropriate daily level. A calcium reactor used with Kalkwasser (limewater aka water with dissolved calcium hydroxide) will drastically help with this.
