Step 4 — Bioactive Color Elements™

Coral color isn't just genetics — it's chemistry.

With your CAM parameters maintained (Step 3), it's time to supply the elements corals use for pigment production and vital biochemical processes. These elements deplete fast through absorption and filtration, so they need consistent top-up — not just for looks, but for coral health, resistance, and growth rate too.

Match the element to the color

Each product targets the elements behind a specific color range. They're made to be dosed together, with Step 5's Bio-Enhance™.

WHITE · BLUE · VIOLET

Bio-Gen™

Iodide, fluoride, and bromide — reduces bleaching, boosts calcification, and supports natural resistance.

Target: 0.06–0.09 ppm total iodine Shop Bio-Gen →

RED · PINK

Bio-Kalium™

Ionic and complexed potassium plus boron — supports nutrient transport and strong aragonite formation.

Target: 375–400 ppm potassium Shop Bio-Kalium →

GREEN · YELLOW

Bio-Metals™

Ionic, complexed, and chelated iron plus manganese — fuels energy production and photosynthesis.

Target: 0.005–0.015 ppm iron Shop Bio-Metals →

Use them as a set. Bio-Gen, Bio-Kalium, and Bio-Metals are formulated to be dosed together — along with Step 5's Bio-Enhance — so your tank gets the full biomolecule and trace-element profile in the ratios corals actually use. Dosing just one covers its color range but leaves the others under-supplied.
