  • Beginner-friendly fertilizer for great plant growth
  • Easy-to-use dispenser for quick dosing
  • Safe for fish, shrimp, and snails

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.

Directions/Specifications

Recommended Dosing Instructions:
1.  For the 500 ml (16.9 oz) bottle, dose 1 pump (1 ml) per 10 gallons of water
—  Dose once a week for low light aquariums
—  Dose twice a week for medium light aquariums

2.  For the 120 ml (4 oz) bottle, dose 2 drops per gallon of water
—  Dose once a week for low light aquariums
—  Dose twice a week for medium light aquariums

We recommend having between 20–50 ppm of nitrate in your aquarium from dosing Easy Green for optimal plant growth.

Guaranteed Analysis:
—  Water Soluble Nitrogen (N) 2.66%
—  Available Phosphate (P2O5) 0.46%
—  Soluble Potash (K2O) 9.21%
—  Water Soluble Magnesium (Mg) 0.7%
—  Boron (B) 0.015%
—  Water Soluble Iron (Fe) 0.13%
—  Water Soluble Manganese (Mn) 0.036%
—  Molybdenum (Mo) 0.00098%
—  Water Soluble Zinc (Zn) 0.0072%
NPK 2.66 - 0.46 - 9.21

Measurable Nutrients: 1 pump of Easy Green in 10 gallons of water adds 3 ppm of nitrate, and 2 drops of Easy Green in 1 gallon of water also adds 3 ppm of nitrate. For more details, see the full article.

Notes:
—  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 poison.org website. For Canadian customers, reference dpic.org.

Perfect fit and high quality.
Size: (Pack of 1)
Good product, not much to say. The product arrived quickly, looks to be of high quality construction, fit perfectly and took me only a couple of minutes to install. I love it when a product is no frills and delivers as advertised. I've used various filters from K&N before and have always had very good success with them so I will be buying more of these for sure when the time comes.

More power, slightly lower (8%) MPG.
Size: (Pack of 1)
Installed on a 2.0 liter Subaru Impreza. I drive up/down the I5 in california 3-4 times a year. For those that don't know there is about a 200 mile flat stretch where everyone runs at 75-85mph. With various filters (FRAM, BOSCH, Subaru OEM), I would consistently get 29.8 mpg. Once I installed the K&N, I could feel the car pulling with a bit more power, but I noticed that I was getting about 27.5 mpg. Totally worth it as the impreza is a little under powered and I don't drive many miles (6k/year) but if you are putting a lot of miles on your car, you may want to have more mpg.
