This is a really pretty alga, it’s my favorite. Hydrodictyon, commonly called “water net,” is a colonial planktonic alga with large cells that are connected to form a reticulate pattern. Colonies can be very large in appearance, sometimes over 40cm wide and up to one meter in length.
Hydrodictyon can be difficult to treat. Significant improvements in treatment efficacy of have been observed by blending the biocatalyst PondZilla Pro into pesticide tank mixes ( i.e. chelated copper, flumioxazine, diquat, endothall). PondZilla Pro improves treatment response time and facilitates the breakdown of dead algal cells. In addition, it is recommended to follow applications with a nutrient removal strategy (Temperature Driven Solutions or MuckBiotics) to reduce nutrients in the sediments and water column due to Hydrodictyon often being found in eutrophic waters.
