Application Information

When to use

For best results, apply early in the season before algae and aquatic weeds begin to develop.

How to use

• Add the required amount straight into the water; the dye will spread naturally through normal water movement.
• Circulation can be enhanced by keeping water features running, which helps the dye distribute more evenly throughout the water.
• Blackout should be applied near the shoreline at various locations around the lake or pond to achieve the best coverage.
• Reapplications of Blackout will help maintain the desired water colour throughout the season.
• This product should NOT be applied to streams, rivers, outflows or water not completely controlled by the user.

Application rate: 2.5 - 5L/ha of water.

Please note: In smaller ponds, you may need to increase the application rate to achieve the required appearance.
