Aquarium Co-Op Easy Potassium 4 oz – Liquid Plant Fertilizer

Aquarium Co-Op Easy Potassium – 4 oz (120 mL)

Potassium supplement for freshwater aquarium plants, especially when an existing fertilizer program does not supply enough potassium. Leaf pinholes can have several causes, so consider overall nutrient conditions.

Manufacturer Dosing for the 4 oz Bottle

Use 2 drops per gallon of aquarium water, adding approximately 2 ppm potassium. Start once per week and assess plant response over two weeks; manufacturer guidance allows adjustment to two or three applications weekly if needed. The 500 mL pump-bottle instructions are different.

Easy Green already supplies potassium and an additional potassium product may be unnecessary for many tanks. Follow all package cautions and avoid overdosing.
