The blue green algae is harmful to the fish farming filed.
1. Cyanobacteria release a large amount of toxic substances after death, which is more harmful than that in vivo
2. Cyanobacteria release some harmful nitrogen compounds during their growth and reproduction, which make them smell like stink water;
3. Most cyanobacteria are not easy to be used by cultured animals, so the growth of cultured animals is slow in the water body with many cyanobacteria
4. Cyanobacteria are easy to float on the water surface, which inhibits the propagation of other algae in the water layer, so the surface water is often clear, the water body's water purification ability is weak, the bottom is easy to stink.
2.The boat filter box with water pump under the filter screen,which can pump the water out, keep the algae in side the box.
The advantage:
1. The long robot arm can easly control and enlarge the collect square on the water suface.
2. The proplusion design with jet water pump under water, this design dont have water splash during vovage. so the tiny algae will keep stable during collect, this can get good collection effection.
