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). 

Please note that we have changed over to dosing caps. Pump heads are still available for purchase.

Signs of Potassium Deficiency

Look for pinholes in your plant leaves. Adding more potassium won't repair current damaged leaves, but it can prevent new leaves that grow from getting holes.

Why Do I Need More Potassium?

Easy Green has high concentrations of potassium in it already. However, some plants such as Java ferns and Anubias like to consume a lot of potassium. Also, sometimes your tap water can be high in nitrates, phosphates, and iron. Your plants love this but are left starved for more potassium. Aquarium fertilizers need to be in balance. Water structure and plant choice can cause the need for additional potassium.

Plants are LOVING it!

Bought Easy Green along with the Potassium and Iron supplements and have seen visible improvements in my plants! LOVE these products! You can see in my photo this established Crypt with the older leaves looking just OK, then the new growth leaves (since starting a weekly dose of Easy Green & Easy Iron & Easy Potassium) coming from the center are just gorgeous lush looking beauty’s!! And this is with Arizona tap water! Nuts!

New leaves!

My Anubias and bucephalandra were stagnant and the day after I started using this, I saw new leaves on several plants. Now that I’ve been using it for five or six months, I see new growth continuously.

Great Boost For Plants!

And my fish room I have many tanks with many different species plants, some with almost all different variety of anubias, in which case I dose heavily with potassium and they love it and are thriving!

Great stuff

As with all of their products, simple, and straightforward. Use 1 ml per week, or twice per week, I think it is and they'll get an additional 9 percent of potassium.

Helping with anubias/fern!

I've historically struggled with java fern, but my java fern trident has done consistently well for coming up on 5-6 months. I attribute much of that success to Easy Potassium.

Anubias savior

When I first got my anubias I had no idea that potassium was the secret to success. Thanks to ACO I learned care for the anubias and they supply a great product to help them grow well!! It last a long time and my anubias are looking great.

Great supplement for Anubias and Java Ferns!

I got this to use as an additional supplement for the Anubias and Java Ferns in my tanks, and it’s working great. Highly recommend this as a great way to provide targeted support for those plants that benefit from higher potassium levels. The dosing cap is very handy as well — it’s much easier to dose correctly for tanks smaller than 10 gallons.

Magic

I have had struggles with Java ferns for a year in all four of my tanks. I added Easy Potassium based on a recommendation from Cory. They are now growing much faster and are getting big after six months. I dose once per week, sometimes twice. I highly recommend this product if your Java ferns seem to be just getting by.

Product Replacement

I purchased the Easy Potassium as a replacement for the discontinued Easy Carbon, which I’ve used for the last 5 years and enjoyed the results. If Easy Potassium works as effectively as Easy Carbon, it will be an awesome transition.

Marked improvement!

I used to really struggle with Java fern, but I’ve been much more successful since dosing easy potassium.

Plants are much happier

Ever since I started adding this to my planted tanks, they seem to be much happier with me :). Great product. Just one critique, I prefer a pump bottle instead of the measuring cup only because I am legally blind and struggle with pouring.
