The hatchery works well just out of the bag, but it is a little loud because of the large bubbles it produces. I drilled out the air opening a little bit and shoved in an air stone that I can easily remove with aquascaping tweezers when its time to harvest.
Very happy with the product and the service.
Thx for your way fast service and great products. The hatchery is easy to use. I had an almost perfect hatch first time out.
So far I have only used this once but it worked very well. As suggested I use an airline control valve and also a one way check valve between the hatchery and air pump. Makes it real easy to harvest the shrimp. The only weak link in the system is the flimsy Diet Sprite bottle I have. Oh for the days of sturdy thick walled plastic soda bottles. When I first screwed the bottle to the hatchery and filled it with water the water started seeping around the threads. Tightened the bottle down firmly and it crushed in from handling. Popped the bottle sides back out and refilled. No leaks and operation fine from then on. My community tank went wild over the brine shrimp. Even the cory cats got in on the feast.
Who doesn’t love a simple way to hatch brine shrimp for fry? Works great and lots of fun. Even the kids joined in to prep for the first batch!
