The way I use has worked great. I take an old quart jelly jar, and I hammer a screwdriver through the lid just making the hole big enough for airline tubing to fit through. Then I slip a line of tubing through it, attach a piece of rigid tubing to it, then I attach a fine mist airstone. I then fill the jar with pre mixed water (8 Tbsp Aquarium salt to 1 gallon water) to the top, add my eggs and close. I turn on the airpump and cover the jar with a damp rag. This will soak up the water that bubbles out the hole in the top. The next day, approximately about the same time I started them the day before, they will be hatched. I personally use San Fransisco Bays hatchery. It is a black box with a 2 ½" hole in the top, and a clear container tube that fits on that hole. The cap of that container has a small hole. When that container is filled with freshwater and set in the hole of the black box, it makes for the only light source of the BBS. They are then attracted to it and venture into the container for easy feeding!! If you don't want to buy the hatchery, I used to use a baby's nose syringe (the kind with the clear tip) and attach airline tubing with an airline tube attachment. I would let the water settle after hatching, then suck out the BBS. Shining a light in one spot would help concentrate them into one area. I hope this makes sense.

Here is a way many other people use - Brine Shrimp Hatchery or

A Do-It-Yourself Brine Shrimp Hatchery

by Matt Lindenfelser, CAKC member

Directions:

1. Attach airline valve to hose and close it. Loop hose over top to prevent backflow.

2. Fill hatchery to within 1 inch of top with brine and artemia eggs.

3. Connect hose to air pump and open valve.

4. If the soda bottles have removable bases, use the second base as a spray shield on top of the hatchery.

To collect nauplii, shut airline valve and disconnect hose from pump. Shine a lamp on the bottom of the hatchery and wait until egg shells have floated and nauplii have gathered at the bottom. Then, move the air hose below water level and open the valve to drain nauplii through a brine shrimp net. Afterwards, close the valve, loop the hose over the top, reconnect to the pump, and open the valve again to resume aeration.

Notes: Water may slowly drip from hole in the cap, but will be caught by the supporting bottle half. You may want to cover the top to reduce salt-spray. Alternately, you may opt to leave the top bottle intact, except for a small hole drilled through its base (although this will complicate cleaning and refilling the hatchery).
