There are two ways to install our brine shrimp hatcher machine.You can use the four suction cup of shrimp incubator to stick it to the tank glass inside or you wanna install it out of the tank glass then you can use the tripod to install out of the tank..
The first way to provide oxygen to the brine shrimp incubator is to put the bubble stone in the incubator to provide oxygen. When the brine shrimp has hatched, open the trim valve at the bottom of the incubator to collect brine shrimp. Note that the direction of the inlet and outlet of the check valve must be installed correctly with the pipe, otherwise the air pump will not be able to discharge air..
The second way to provide oxygen to the brine shrimp from the bottom hole of the incubator. Please note the direction of the inlet and outlet of the check valve and the pipe must be installed correctly, otherwise the air pump will not be able to output air, and the trim valve needs to be opened. When the brine shrimp has hatched, first turn off the trim valve, then pull out the air pump tube from the trim valve, and then open the trim valve to start collecting brine shrimp.

ACCURATE AND FAST This oxygen monitor can accurately determine your SpO2 (blood oxygen saturation levels), heart rate and pulse strength in 8 seconds and display it conveniently on a large digital LED display..
SPORT ENTHUSIASTSSuitable for mountain climbers, skiers, bikers, aviators or anyone interested in measuring their SpO2 and pulse rate while on the move. You should only use the pulse ox before or after your exercise. Also, you must remain stationary while the pulse oximeter measure your pulse rate and SpO2 levels.This device is for sports and aviation use only..
