    Acid Buffer™ - Non-Phosphate pH Reducer for Aquariums Overview:Acid Buffer™ is a non-phosphate buffer specifically designed to lower pH in aquariums, particularly those with plants or very hard water. By avoiding phosphates, it helps prevent algae growth and water cloudiness. When used with Alkaline Buffer™, it buffers pH levels between 6.0 and 8.0, creating an ideal environment for aquatic life. As Acid Buffer™ lowers pH, it also converts carbonate alkalinity (KH) into available CO₂, supporting photosynthesis in aquatic plants. Key Features: Phosphate-Free: Prevents algae proliferation and maintains water clarity. pH Buffering Range: Stabilizes pH between 6.0 and 8.0 when combined with Alkaline Buffer™. Promotes Plant Growth: Converts KH into CO₂ for enhanced photosynthesis. Ideal for Hard Water: Effective in environments where phosphate buffers are unsuitable. Sizes Available:70 g, 300 g, 600 g, 1.2 kg, 4 kg

    Product Overview: Catappa Leaves Catappa leaves, sourced from Indian Almond Trees (Terminalia catappa), are a natural and effective way to replicate the native environments of bettas, shrimp, and other aquarium inhabitants. These leaves provide both aesthetic and functional benefits for aquariums by releasing beneficial compounds and creating conditions similar to acidic water habitats rich in leaf litter. Key Benefits: Natural tannins release: Catappa leaves release tannins and organic compounds that help to lower pH and gently tint the water, mimicking natural blackwater conditions. Encourages healthy ecosystems: As the leaves decay, they promote the growth of beneficial microorganisms, providing a natural food source for shrimp, snails, and fry (newly-hatched fish). Habitat replication: Creates an environment similar to those with abundant leaf litter, promoting comfort and well-being for aquarium inhabitants. Ideal For: Bettas Shrimp Snails Newly-hatched fish Catappa leaves are an excellent addition to aquariums, enhancing both the water quality and the overall health of aquatic life.
