Neck & shoulder Heating Pad is a specific type of heating pad, which is used for curing pains and fatigue happening to human neck & shoulder.
It has a detachable controller, with 4 heat setting options.
Normally it will shut off automatically after 2 hours, for the sake of human safety.

First, the pool of wintering ponds should be lower than the ground level, located in the leeward sunny place. It is necessary to ensure adequate water supply, facilitate water injection and drainage, and control the water depth to more than 1.5 meters. Warm water fish must also ensure timely supply of hot and cold water. The water quality should be fresh, the amount of dissolved oxygen should be above 10 mg/l before icing, the ice age should be kept at about 5 mg/l, and the pH should be between 7.5 and 8.5. At the same time, it is required that the clay in the bottom of wintering pond be compacted to ensure that the bottom of the pool is flat. , good water retention performance. For tropical warm water fish, plastic greenhouse insulation must be built on the pool. The pond area is slightly larger, generally between 2 and 5 acres, to use large pool ponds, etc. Warm-water fish also depend on the amount of hot water, water temperature and insulation measures. Generally, 350 to 450 kg of fish can be stocked per mu. Ponds with good conditions can also be stocked up to 500 kg or more.
Second, in order to ensure the safe wintering of fish, Qiupei must be intensively cultivated in the fall. The fish ponds dominated by earthworms and cockroaches should be fertilized by water and can also be fed with concentrate feed; the grass carp-based fish ponds should be fed first with duckweed, Water grass and other green materials, then feed the fine material. The tropical warm-water fish mainly concentrates, and guarantees the fat content and the sugar content in the feed, supplemented by the feeding of the cake, ensuring that the fish is fattening and strengthening its cold and disease resistance.
Third, quarantine fish before the wintering pool, first clear lime sterilized pond, after the efficacy of fish into the pool. When immersed in the pool, first dip the fish body with 5% salt solution for 5 minutes. During the pooling process, care should be taken to avoid fish bruises, bruises, or step injuries. Injury can be applied to the wound at the time of the application.
Fourth, the amount of stocking for wintering ponds depends on the area, area, water depth, oxygen content, variety, specifications, and ventilation. Appropriate feeding, increase the nutrients of the water body. When the weather is fine, the feed can be fed properly. Before freezing, organic fertilizer should be added to ensure the water body fatness. Day and night patrol pond. Ensure that there are dedicated personnel on duty, feeding, measuring water temperature and dissolved oxygen, and find problems in a timely manner. If zooplankton grows excessively, you may replace the pool water or kill it with a bleach solution; always inject new water and keep the water depth 1.5 meters or more. Maintain a good wintering environment. To ensure that the pool is quiet, pedestrians are prohibited from crossing the pool; sewage pesticides are prohibited from entering the pool and water pollution is prohibited; poultry and livestock are strictly forbidden from entering the pool and measures are taken to kill snakes, cockroaches, rats and steal fish and birds. Prevent fish diseases. First of all, we should do a good job of water circulation, change the water once a week, each time changing the water 1 / 3; next weekly bleaching solution Quanchiposa 1 disinfection; occurred fish disease to symptomatic medicine, timely diagnosis and treatment, found dead fish should be promptly Anatomy of the diagnosis of the cause and the dead fish away from the fish pond deep-seated treatment; frequent cleaning of the table, remove weeds and debris in the pool.
Fifth, management must be diligent in observing the water conditions to ensure that the water temperature, warm water fish temperature control between 16 °C ~ 20 °C, water injection to prevent the temperature difference is too large; to ensure water quality, water color to clarify as well, the water becomes black The brown color indicates that the water quality has deteriorated, and the water or oxygen must be added in a timely manner; to ensure the dissolved oxygen in the water, it should be measured once every 3 days, and oxygen should be promptly increased at about 3 mg/l. The second is diligent in sweeping snow and ice or uncovering the coverage of plastic greenhouses. Snow removal from the ice area can ensure the light in the water layer under the ice to enhance photosynthesis, and it is also necessary to break the surface ice layer to increase dissolved oxygen in the water. There are plastic greenhouses that cover the deep water insulation in winter when the weather is fine.
Now that it has entered the fish winter season, how to ensure the safe wintering of fish is a major event for the vast number of fishermen and aquaculture units. The following wintering precautions for cold-water fish and warm-water fish are described below for reference.
