Features: 1.Upgraded version, amphibious (inside and outside the tank). Incubate as you like, put it where you want. 2.Simple, practical, convenient to hatch shrimp for feeding fish. Easily harvest shrimp without muddy water. 3.The process is very simple, easy to operate and use, and high incubation rate. 4.Made of premium plastic material, non?toxic and durable. A good and wise choice you should make. 5.The suitable temperature is 25?28 degrees, can be used directly in the tank. Specification: Item Type: Shrimp Eggs Hatcher Incubator_x000D_ Material: Plastic_x000D_ Weight: Approx. 238g / 8.4oz_x000D_ How to use:_x000D_ 1. The clean water is aerated first, and then 90% aerated treated water is injected into the tank of the incubator, and then about 10g of coarse salt is added to the tank water to dissolve in advance._x000D_ 2. Connect the aeration pump to the air inlet at the bottom of the incubator, adjust the air volume to an appropriate size, and the appropriate temperature is 28-30._x000D_ 3. Put in about 3-5g of brine shrimp eggs and after about 36-48 hours (depending on the incubation temperature and the quality of brine shrimp eggs), it can hatch smoothly._x000D_ 4. Collection operation: After the brine shrimp eggs hatch, stop oxygenation and let stand for about 10-15 minutes. The brine shrimps to be hatched sink to the bottom and the shrimp shells float, and the brine shrimp larvae can be collected from the bottom of the incubator, and small fish can be fed. ._x000D_ 5. Please store uneaten brine shrimp larvae in the refrigerator and freeze._x000D_ 6.The top input of the simple brine shrimp egg incubator is the air supply port. Please adjust the input air volume yourself. If the input air volume is too large or too small, it will affect the hatching time and survival rate of the brine shrimp eggs. Please adjust the input air volume with the air adjustment switch._x000D_ 7. The air supply port on the top needs to be connected with a simple check valve, which can effectively prevent backflow of water in the incubator and prevent damage to the air pump._x000D_ 8. It can be installed in the tank for incubation with a constant temperature in the tank. PackageList: 1 x Incubator 1 x Outlet Pipe 1 x Bubble Stone 1 x Check Valve 1 x Base 1 x Bottom Air Pipe 2 x Hanger 4 x Suction Cup Note Because tropical fish need to be heated to between 25 and 30 degrees in winter, the brine shrimp incubator can be used directly in the fish tank, which is conducive to hatching and increasing the survival rate. The incubation temperature: the brine shrimp eggs can be within the range of 7?30 degrees Celsius Incubation, the incubation speed increases with the increase of temperature. The suitable temperature for incubation is 25?30. Salinity: Different types of brine shrimp eggs have different requirements for salinity during hatching. Before hatching, place the eggs in fresh water (mineral water can be used) for 30?60 minutes to make the dehydrated eggs fully absorb water, and then move the eggs into artificial seawater with a salinity of 3% for incubation. It is recommended to use sea salt when preparing artificial sea water. The reason is that sea salt contains many kinds of ions, which is beneficial to larval shell breaking.
