  • Potassium supplement for enhanced plant growth
  • 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.

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.

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.
