Tetra FloraPride promotes the growth of floating and rooted aquatic plants through a combination of nutrients including potassium and iron. FloraPride is a vital compliment to substrate fertilizers as part of a complete plant care program. The addition of this aquatic plant fertilizer will ensure that your aquatic plants sustain a healthy and lush root system. Simply add two teaspoons to every ten gallons of water. When the tanks are cleaned and the water is changed, the tank will require another dosage.
