MULTIELEMENTS A and B is a combination product with special macro- and trace elements, specifically developed for the complementary use with calcium reactors or unbalanced two part addition methods.
When using calcium reactor or simple two part addition methods for calcium and carbonate supply in reef tanks, important macro- and trace elements are going to be limited as these are not contained in the media used. They need to be supplied separately.
MULTIELEMENTS are intended for direct supplementation in the reef tank. We recommend regular adding with the help of dosing pumps.
