In a closed reef, waste raises both nutrients. High levels feed hair, brush, and slime algae, and can brown or stress corals.\u003c\/p\u003e\n\u003cp\u003eIt is a blend of carbon sources and organically bound elements. It feeds nutrient-reducing bacteria already in the tank, speeding denitrification (nitrate to nitrogen gas) and phosphate processing. It does not bind nutrients chemically and strip them in one hit.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eControllable reduction:\u003c\/strong\u003e Daily dosing lets you lower or hold nutrients gradually instead of shocking the system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoral colour:\u003c\/strong\u003e Lower, stable nutrients can reduce excess zooxanthellae so brown tissue shows more of the coral’s own colour.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth:\u003c\/strong\u003e Excess nitrate and phosphate can slow stony coral skeleton growth; keeping them in range supports normal growth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReef-safe when used as directed:\u003c\/strong\u003e Formulated not to harm copepods, amphipods, and other beneficial microfauna.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaily liquid:\u003c\/strong\u003e Concentrated for ongoing dosing rather than a one-off media reactor.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWater and system compatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater:\u003c\/strong\u003e Marine and reef aquariums only.
