Provide an Essential Macronutrient for Your Plants
- 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.

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!
