Skimz has a new line of reef aquarium additives called the Reefcare System with an easy color-coded naming convention. SPS Coral is the name of the liquid additives which will come in a Blue for Iodide, Green for Iron, Red for Potassium, Gro for Strontium and Purple for Iodide and Strontium. Skimz is marketing these SPS Coral additives as having a direct benefit to SPS coral color even if most of these ions are really for the benefit of the whole reef chemistry. More information can be read on the Skimz Additive webpage.
