If you only get one fertilizer for your aquarium plants, then Easy Green is the one you want. As our #1 best-selling product, this all-in-one liquid fertilizer contains all the essential nutrients your aquatic plants need to thrive so that you don’t have to figure it out yourself. Cory, the founder of Aquarium Co-Op, originally developed it for in-store use because he wanted something that was:

1.   Easy to use, without having to measure out a ton of different supplements
2.   Way more potent than what was available on the market
3.   Reasonably priced, because a little goes a long way

While other brands require you to measure out certain milliliters or capfuls, we offer two sizes of Easy Green 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. Just dose 1 pump per 10 gallons of water each week to get great-looking plants for less than a penny per gallon. For nano tanks smaller than 10 gallons, the 120 ml bottle with the dropper cap is perfect and treats 1,200 gallons total.

If you’re new to planted tanks or aren’t getting the results you want, give Easy Green a try. This tried-and-true fertilizer has thousands of 5-star reviews that you can read below to see the incredible results people are getting.

—  Store the fertilizer upright and away from children. The pump head is not leakproof. For optimal shelf life, store the fertilizer out of light.
—  Keep the tip of the pump clean of debris. Wiping the pump tip after each use helps prevent a mineral crust from developing. If the pump gets blocked up, it can cause the fertilizer to spray in a random direction, so run the pump head under warm water until the blockage melts away.
—  Warning: fertilizer can be irritating if it gets into your eyes, nose, or mouth, and it can cause stomach upset if swallowed. If you get Easy Green on your skin, rinse it off. If you get it in your eyes or mouth, rinse thoroughly for 15 minutes. For USA customers, reference the website.
