By shading the water column, it limits photosynthesis in submerged algae and aquatic plants, thereby helping to control their growth and improve overall water quality. Suitable for ponds, dams, and lakes, Aquatic Blue also enhances visual appeal and helps maintain cooler, oxygen-rich water conditions for healthier aquatic environments. ### Key Features and Benefits - Reduces UV and visible light penetration to suppress algae and aquatic weed growth - Safe for use around fish, livestock, pets, wildlife, and aquatic plants - Improves water clarity and visual aesthetics - Non-toxic, biodegradable and environmentally friendly - May help stabilise pH and increase dissolved oxygen levels by reducing water temperature - Compatible with other herbicides for integrated weed management programs ### How It Works Aquatic Blue filters out red–orange (590–750 nm) and blue–violet (380–495 nm) wavelengths of sunlight. This reduces the light available for photosynthesis, effectively shading the photic zone and slowing the growth of submerged weeds and algae. ### Application Rates Where to Use How Much to Use How to Apply How Often to Apply Ponds (max. 1 m depth) 7.5 mL per 1,000 L of water Pour directly into water or dilute 1 part Aquatic Blue to 10 parts water and spray evenly Every 4–6 months Dams & Lakes 5 L per 2 ML of water Apply directly or pre-dilute as above for even dispersion Every 4–6 months ### Suitable For - Fish ponds (0–15,000 L) - Small ponds (0–20 m²) - Large ponds (15,000–50,000 L) - Small dams (50,000 L–1 ML) - Large dams and lagoons (1–10 ML) - Lakes (10 ML +) ### Safety and Environmental Information Aquatic Blue is non-toxic and safe for swimming, irrigation, and livestock watering when used as directed. It does not stain skin, hair, rocks, or sand once diluted. Over time, the dye breaks down naturally through photodegradation and dilution. ## Specifications - **Suitable For:** Nursery + Turf + Landscape + Protected Cropping ## Documents - [SDS - Aquatic Blue - 240701](https://fernland.com.au/documents/404/) - [Brochure - Aquatic Blue - 251105](https://fernland.com.au/documents/537/) - [Literature Review - Aquatic Blue - 251105](https://fernland.com.au/documents/682/)
