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).
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.
Fish, Shrimp, and Snail Safe!
Like all of the Aquarium Co-Op fertilizers, Easy Potassium is completely safe for fish, shrimp, and snails.
Seemingly has gotten rid of the pinholes in the leaves and the coloration is great.

Great for java fern and anubias
Since I started supplementing this with easy green, java ferns and anubias have really began to thrive. My java ferns do not have dark spots anymore and the anubias have began flowering.

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.

Awesome Product
I love easy green but I needed a little extra potassium for my anubias and java fern. This stuff is great along side easy green.

Easy like I need!
As a mother of a toddler who is trying to be involved in the hobby, I need easy. I love the easy pump head fertilizers from the Co-op. I’m finally setting up a new tank with a more variety of plants, but currently Anubias is in all my tanks and they had the pin holes. Using this to help support them with their new leaves and it’s working!

Perfect!
I am so glad this exists. I had been neglecting my Java ferns and Anubius because the easy green has nitrates that I don't need with my current fish load. Now I just need an easy micros to replace my seachem one and I'll be set. I can already see better growth on my new leaves. Happy plants, no algae. Mind you, my tank is 75G and gets a 25% water change quarterly. It's been in balance for years.
