Brine Shrimp Hatchery

This is my version of a Brine Shrimp hatchery. I'm using separatory funnels that I bought on eBay. I use one to do a large batch to feed during the day and the other to do a small batch to feed at night for the nocturnal things I have. So far it has worked really well. I use the same principles as in Marcs' thread on his Hidden Treasures page. I open the valves at the bottom to drain of the hatched shrimp leaving the shells floating at the top. I thought it was kind of neat to come up with something different to see how how it would work.

I also have a 5 gal. tank that I use to grow out some shrimp occasionally just to feed as a treat. I only use spirulina to grow them out. They're slow to grow the first week, but the second week they grow really fast. By the end of the second week they're ready to feed. They get as big as any you see around town. My fish love them. I didn't have much luck growing them out until I started using spirulina. Since then, I haven't lost a batch.

I just started these in the picture. They'll be ready in 48 hours. This will be my fourth batch since putting this together.
 
Can you pass on some details as to size of funnels used and size of air pump? Anything you feel would assist someone in duplicating your setup.

The separatory funnels are 10" from top to bottom. They hold about 1 1/2 to 2 cups of water. I made the stand out of egg crate and it's held together with plastic ty wraps. It's good and sturdy. The pump is very small 2" x 2", about the size of an egg. It says Hawkeye 201 on the side of it. Think I got it at Wal-Mart. I had it laying around. I would just get the smallest pump you could find. Hanging on the top right corner of the stand is a valve assembly I got at Wal-Mart. The pump connects into it and it has to supply valves out so that I can control the air to each separatory. It's just regular old air line tubing. You want just enough air bubbles to keep the water moving very gently. If you have anymore questions, just ask.
 
Hey,
Inquired at a lab equipment place about the sep funnels and was told they are considered instruments of crime used in the manufacturing of drugs and not sold to the general public....WOW. :shock: I was expecting a police car to pull up any minute. I guess e-bay is the only source, all the one's I found were Big Money . Which site did you get these on and if ya don't mind...what did you pay for them :?:
 
Yea - I saw those, they want a few coins for them. I'll save up my allowance and get a couple one day. :oops: Guess I'll be using the 2 liter bottle method for a while.
:cry:
Cheers :!:
