Which statement about Aquashade is true?

• A. It controls submerged vegetation and algae, does not work on floating algae mats, and can be poured directly into the water.
• B. It controls only floating algae mats.
• C. It cannot be poured into water.
• D. It is never permitted in a public water supply watershed.

Answer: (A)

Aquashade works by coloring the water to reduce light penetration, which slows photosynthesis for aquatic algae and submerged vegetation. Because the growth of these organisms depends on light reaching the submerged parts of the plants and algae, shading the water is an effective way to suppress their growth.

That’s why the statement is true: it targets submerged vegetation and algae through this light-limiting approach. Floating algae mats sit on the surface and may be less affected by light reduction deeper in the water column, so Aquashade is not relied on to control those mats.

Aquashade is applied by pouring it into the water, following label instructions for dilution and rate. So it can be poured directly into the water as part of its approved use.

The other statements are not accurate because Aquashade is not limited to floating mats, it can be poured into water when used as directed, and it is not categorically prohibited in a public water supply watershed; such applications are allowed under label guidelines with proper precautions.
