It delivers ionic and complexed calcium along with magnesium, strontium, barium, iron, manganese, and other trace metals, the building blocks corals use to grow strong aragonite skeletons and hold their color. Paired with Easy Z, it gives a reef the full range of major, minor, and trace elements without the fuss of a six-bottle dosing routine.

As your reef grows it pulls calcium out of the water continuously, and a tank that runs low on calcium slows down and loses color. Easy E replaces that calcium in ionic and complexed forms for fast and sustained availability, and it carries a suite of trace elements along with it. The result is steady growth and better coloration when dosed consistently and balanced against alkalinity.\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\u003eIonic and Complexed Calcium\u003c\/strong\u003e\u003cspan\u003eConcentrated calcium at 110,000 ppm for fast plus sustained uptake.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eFull Trace Suite\u003c\/strong\u003e\u003cspan\u003eMagnesium, strontium, barium, iron, manganese, vanadium, and molybdenum.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eBuilds Aragonite\u003c\/strong\u003e\u003cspan\u003eSupplies the calcium corals use to grow strong skeletons.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eSupports Color\u003c\/strong\u003e\u003cspan\u003eThe trace metals carried with the calcium help corals hold their color.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eTwo-Part Simplicity\u003c\/strong\u003e\u003cspan\u003eEasy E plus Easy Z covers your dosing without a six-bottle routine.\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.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eDosing\u003c\/h2\u003e\n  \u003cp\u003eAdd Easy E into an area of high water flow, ideally on the opposite side of the tank from where you dose Easy Z.
