Laguna Liquid Peat naturally filters out sunlight in pond water creating optimum water conditions. It includes a natural peat extract which contains a gentle and natural-occurring anti-fungicide that helps prevent fungal infections on fish while lowering pH in alkaline ponds. When administered at the recommended dosage, it produces a pleasant amber tint that serves as a perfect contrast to the rich colors of pond Goldfish and Koi while giving fish a feeling of protection. Laguna Liquid Peat treats 3,749 gallons of water and quickly creates ideal water conditions for fish and plants.
