Potassium is a very important macronutrient for planted aquariums. If aquatic plants don't get enough of this nutrient, they can develop distinctive pinholes that are sometimes rimmed with brown or yellow. While Easy Green all-in-one fertilizer already contains plenty of potassium for most planted tanks, Easy Potassium is a useful supplemental fertilizer for people who are running high light planted tanks with CO2 injection or have lots of potassium-hungry plants (like java fern and anubias).

While other brands require you to measure out certain milliliters or capfuls, we offer two sizes of Easy Potassium that come with easy-to-use dispensers for quick dosing. For most planted aquariums, get the 500 ml bottle with the pump head that treats 5,000 gallons total. For nano tanks smaller than 10 gallons, the 120 ml bottle with the dropper cap is perfect and treats 1,200 gallons total.

Easy Potassium

Absolute W. If your tap water is rich in nutrients like mine - over 10 ppm nitrates out the tap with significant phosphate dosing extra potassium is a must. The one flaw to the easy line is fixed. Now there is no argument to be made. The easy line is the best line of ferts on the market, and can work for every tap water imaginable. Every co-op product is vastly superior to every competititor and Cory has contributed more to this hobby than anyone except the inventor of glass, tacashi Amano, and God for creating fish and plants
