Simply put this is the best brine shrimp hatchery on the market. You may be thinking how much better could this be over a 2 liter bottle? When you hatch live baby brine shrimp every day, the construction and thoughtfulness of the design won't go unnoticed. All of team Aquarium Co-Op use and love this hatcher. Made of super strong plastic to withstand an impact. It has the option to run a heater and thermometer in it. We highly recommend running this brine shrimp hatchery with our USB Air Pump.
***We don't use the provided airstone in our setup as it makes cleaning harder between hatches. If you wish to use the airstone you'll need to cut down the rigid tubing.
