Aquashade® Liquid Pond Dye is an EPA-registered Aquatic Plant Growth Control designed to limit underwater weed and algae growth by filtering sunlight before it reaches the pond bottom. Its concentrated blue and yellow dyes block specific light wavelengths that fuel photosynthesis, helping suppress submerged weeds and algae when applied early and maintained throughout the season. Beyond its plant-control benefits, Aquashade also transforms water with a crisp, clear, aqua-blue color, giving ponds and decorative water features a clean, vibrant appearance.

For best results, apply Aquashade in early spring or early summer, before aquatic growth begins. Use 1 gallon per acre at 4 ft depth, pouring the dye directly into the pond. The product disperses on its own within hours through natural water movement, and may be reapplied every 1–4 weeks as color fades due to sunlight breakdown. Aquashade is most effective in ponds with minimal water inflow/outflow, and becomes less effective when weed growth has already reached within 2 ft of the surface. Always treat the full pond volume for consistent shading and season-long clarity.

Please note that water treated with Aquashade should not be used for human consumption, and some states may require a permit to use this EPA-registered product. Avoid storing the concentrated dye on carpeted surfaces, and clean accidental spills from skin or clothing using bleach or a chlorine-based cleaner. For pond owners seeking both aesthetic enhancement and effective, preventative aquatic plant suppression, Aquashade® delivers proven results all season long.
