Aquarium Co-Op offers a comprehensive range of top-quality aquarium plant supplies for planted tank enthusiasts, focusing on everything needed to create a thriving underwater garden for your fish, shrimp, and snails. We started this company to help make aquariums easy for hobbyists, and one of the first products we developed is our bestselling Easy Green aquarium fertilizer. If you only get one aquarium fertilizer, this Aquarium Coop fertilizer is the best liquid fertilizer for aquarium plants because of its balanced, all-in-one formula and concentrated nutrients that grow lush, healthy underwater flora at an affordable price. Not only is it one of the best aquarium fertilizer on the market, we use ammonia-free, nontoxic ingredients to ensure it’s the best aquarium plant fertilizer safe for fish, shrimp, and snails.

Given the popularity of our Easy Green liquid aquarium plant fertilizer, we also developed the Aquarium Co Op fertilizer line that includes Easy Iron to bring out the color in red aquatic plants, Easy Potassium for aquariums filled with heavy potassium feeders like java fern and anubias, and Easy Root Tabs for root-feeding plants such as Amazon swords and cryptocoryne plants. Check out our thousands of 5-star customer reviews to see why Aquarium Co-Op makes the best fertilizer for aquarium plants.

In addition to our fertilizer options, Aquarium Co-Op provides a wide array of aquascaping tools — like planting tweezers, curved scissors, and super glue gel — designed to make planting and maintenance a breeze. Also, don’t forget the importance of finding the best light for planted aquarium setups for different tank sizes and care requirements. Based on our experience of running all kinds of planted tank light brands in our home and store aquariums, we’ve curated a collection of the best planted aquarium light solutions so that your aquatic plants have robust growth and vibrant colors.
