Fauna Marin Multi Elements B
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.

I’ve been using Multi Elements B with my calcium reactor for three months. My water parameters have stayed stable, especially the trace elements that were previously fluctuating. The dosing pump works smoothly and I don’t need to worry about missing doses.
Jennifer Mathis –
It’s a reliable supplement that fills the gaps left by calcium reactors. I noticed better coral growth after adding it regularly. The instructions are clear and the product is easy to dose.

After switching from a two-part addition method, I found my trace elements were low. Multi Elements B solved that issue. I now maintain consistent water chemistry and my live rock looks healthier.
