Aquascape Natural Pond Tint safely tints pond water a natural tea color, helping to shade the pond and create a shimmering effect across the water. Natural Pond Tint also contains humic acid and enzymes that help to balance the pond ecosystem, significantly reducing pond maintenance required throughout the year. It's ideal for use in the spring when pond plants have not started growing and shading water from sunlight, or summer when water temperatures start to rise. One dosage will last up to 6-weeks. The easy-to-use pump top accurately measures 100 gallons of treatment per pump and the full 8-ounce bottle treats 5,000 gallons. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
