There are snails in the aquatic plant tank, which is caused by the fact that the newly moved aquatic plants were not disinfected before implantation, and the snails and unhatched eggs attached to the aquatic plants after implantation continued to hatch and reproduce.
The method of killing Oncomelania hupensis is as follows:
1. When the lights are turned on in the morning and turned off for one hour at night, snails attached to the pool wall and aquatic plants are sucked out by inflatable air ducts. After repeated several times, you can get good results.
2. Kill snails with "eight-character doll" fish. Put the eight-character doll in it to eat snails. When you can't see snails, you should fish them out and raise them separately. Otherwise, when there are no snails to bite, they will bite shrimp or aquatic fish in the aquatic plant tank, so pay special attention.
3. Drug killing:
A. Newly purchased aquatic plants can be put into a disinfection treatment pool, and snails and newly hatched snails can be killed after about 10- 15 days, and then moved into an aquatic plant pool.
The simplest disinfectant is "potassium permanganate" or "copper sulfate", which can be purchased from aquariums or chemical raw materials companies.
B. When there are fish and shrimp in the aquatic plant pond, in order to kill the snail, chemical germanium agent or natural organic germanium (Ge) can be used to break the snail shell to death without harming the aquatic plants, fish and shrimp and nitrifying bacteria.
Snails eat algae, but only the most tender new algae. Algae-forming algae and steel algae (old algae) do not eat, and the algae they eat are very limited, which has little effect on algae control.
