This decay allows the buds (turions) to become detached and spread planting themselves in the sediment. During the decay sufficient levels of nutrients can occur making some areas devoid of oxygen. Low oxygen can cause fish kills and foster blue green algae growth (unsafe for dogs). Lack of oxygen can also lead to chemical reactions resulting in once-sequestered phosphorus being released from sediment.<\/p>\n\n\n\n<p>It is important that any control of curly-leaf pondweed not damage native plants, but rather maintain or increase their abundance. Abundant and diverse native aquatic communities host a variety of helpful organisms. A diverse aquatic plant community can help sustain water clarity by providing a refuge for zooplankton (food for fish), sequestering nutrients (phosphorus for example), reducing sediment resuspension (muddy water), and decreasing algae abundance.<\/p>\n\n\n\n<p>Treatment chemicals = Aquathol K (&gt; 3 ppm used in 2022 with reduced areas due to flowing water.
