When it runs low, older leaves develop very distinctive pinholes, often rimmed with brown or yellow, and those holes keep growing until the leaf decays away. Easy Potassium replaces that potassium directly so your plants can keep building healthy new growth. In most tanks Easy Green provides plenty of potassium on its own, but high-light, CO2-injected, and heavily planted tanks often want the extra boost.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv class=\"aq-features\"\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003ePure potassium\u003c\/strong\u003e\u003cspan\u003eTargets potassium only, with no added nitrogen or phosphorus.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eStops pinholes\u003c\/strong\u003e\u003cspan\u003eClears the brown-rimmed pinholes and yellowing of K deficiency.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eFor hungry tanks\u003c\/strong\u003e\u003cspan\u003eIdeal for high-light, CO2, and heavily planted setups.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eLivestock safe\u003c\/strong\u003e\u003cspan\u003eSafe for fish, shrimp, and snails when dosed as directed.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eWon't spike nutrients\u003c\/strong\u003e\u003cspan\u003eAdds potassium without raising nitrate or phosphate.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"aq-feature-card\"\u003e\n\u003cstrong\u003eAquarium Co-Op quality\u003c\/strong\u003e\u003cspan\u003eMade in the USA by Aquarium Co-Op.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch2\u003eHow to Dose\u003c\/h2\u003e\n\u003cp\u003eEach dose adds about 2 ppm of potassium.
