- Easy-to-use measuring cap for accurate dosing

Safe for fish, shrimp, and snails
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.

Customer Reviews
Love this stuff especially for my Anubias and ferns they love this
My Java ferns used to have black holes and not look very good. I always wondered how could people consider it an easy plant. I started adding Easy Potassium to the tank and my Java Ferns now look good! Slowly getting rid of the old leaves that still look bad, but the new ones look amazing! Also, Anubias are growing so much faster! I have one nana petite that is now almost the size of the palm of my hand! Highly recommend the easy potassium!
Seemingly has gotten rid of the pinholes in the leaves and the coloration is great.
My Anubias flowered after just 4 weeks of adding Easy Potassium to my biweekly Easy Green regimen
I'm getting the bigger bottle so it lasts longer!
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.
My 200 plus Anubias plants are doing even better since I started using this👍
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.
Needed a Potassium supplement for enhanced plant growth…I like the Easy-to-use dispenser for quick dosing…will repeat order for sure!
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.
