It supplies complexed potassium and boron, two elements corals lean on for warm-toned pigments and healthy skeletal growth. Potassium works as a nutrient transporter that helps move color-building compounds through coral tissue, while boron supports the aragonite corals use to build their skeletons. If your red planet, pink birdsnest, or rainbow acros have lost their warmth, this is the potassium boost that brings them back.

Potassium acts as a nutrient transporter inside coral tissue, helping shuttle the building blocks of warm-toned chromoproteins where they are needed. Boron rounds out the formula by supporting aragonite production, the calcium carbonate skeleton corals grow on. Both elements are drawn down steadily in a busy reef, so Bio-Kalium keeps them topped up between water changes and lets your reds and pinks hold their intensity.\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 Red and Pink\u003c\/strong\u003e\u003cspan\u003eFormulated to intensify the warm-toned pigments in LPS, SPS, and soft corals.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eComplexed Potassium\u003c\/strong\u003e\u003cspan\u003eA stable, bioavailable potassium source the corals can readily use.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eNutrient Transporter\u003c\/strong\u003e\u003cspan\u003ePotassium helps move color-building compounds through coral tissue.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eBoron for Skeleton\u003c\/strong\u003e\u003cspan\u003eSupports aragonite production for strong, steady skeletal growth.\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    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003ePart of a System\u003c\/strong\u003e\u003cspan\u003eDesigned to run with Quantum Bio-Enhance, Bio-Gen, and Bio-Metals.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eDosing\u003c\/h2\u003e\n  \u003cp\u003eAdd Bio-Kalium into an area of high water flow.
