It supplies bioactive halogens, iodide, fluoride, and bromide, the elements corals use to drive their cool-toned pigments and chromoproteins. Beyond color, Bio-Gen helps reduce coral bleaching, supports calcification, acts as a natural resistance booster, and feeds beneficial macroalgae. If your blue tenuis, purple stylo, or hammer tips have faded toward brown, this is the halogen boost that brings them back.

In closed reef systems iodine is consumed quickly by corals, macroalgae, and protein skimming, so it runs low between water changes and the cool tones fade. Bio-Gen replenishes iodide, fluoride, and bromide in bioactive form so corals can keep building those pigments. The same halogens support healthy calcification and help corals resist bleaching stress, which is why Bio-Gen does more than just boost color.\u003c\/p\u003e\n\n  \u003ch2\u003eFeatures\u003c\/h2\u003e\n  \u003cdiv class=\"aq-features\"\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eTargets White, Blue and Violet\u003c\/strong\u003e\u003cspan\u003eFormulated to intensify the cool-toned pigments and chromoproteins in LPS, SPS, and soft corals.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eBioactive Halogens\u003c\/strong\u003e\u003cspan\u003eSupplies iodide, fluoride, and bromide in a readily available form.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eReduces Bleaching\u003c\/strong\u003e\u003cspan\u003eHelps corals hold their zooxanthellae and resist bleaching stress.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eSupports Calcification\u003c\/strong\u003e\u003cspan\u003eAids the calcification process for steady skeletal growth.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eFeeds Good Macroalgae\u003c\/strong\u003e\u003cspan\u003eEncourages the beneficial macroalgae you actually want in a refugium.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eDosing-Pump Ready\u003c\/strong\u003e\u003cspan\u003eStable liquid that runs cleanly through any auto-doser for daily dosing.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eDosing\u003c\/h2\u003e\n  \u003cp\u003eAdd Bio-Gen into an area of high water flow.
