Almond leaves provide a natural and attractive way to maintain slightly acidic pH levels in freshwater aquariums.
Small size is roughly 4-5"
Medium size is roughly 6-8"
Large size is roughly 9-11"
Crushed comes in a 2 oz. (approx.) bag. Boil the crushed leaves to extract the tannins and strain to create an acidic "tea" which can be added directly to an aquarium to help lower the pH.
Great product. Great quality.
