I bought several 1 litre water carriers (Payless Plastics) and found a small tupperware container that fits the 4 1litre containers in snuggly. I leave the caps on, chop the bottoms off and invert them in my tupperware water bath. Fill them with tap water at 26°C, fill the tupperware container, add a small heater at 28°C. Next I add air pump, four lines connected to 4 glass pipettes (glass tube) and dropped to the bottom of each water carrier. The flow is controlled to turn the water over gently.
I add two tablespoons of sea salt, a cap full of BBS and my wifes bedside lamp (40watt).
Approximately 24 hours later I check their progress with a turkey baster. Suck the little critters up and you can see them swimming in the light. If all is well, I turn off the air, let them settle, siphon off the shrimp into a large wine glass which contains clean water. They settle quickly and I suck a portion with the baster and dangle it in the tank. BBS swim from the saline solution into the waiting freys mouths and later I remove the baster and empty its contents down the drain.
Most breeders suggest not to use air stones for raising BBS. I hope this helps.
And finally the wife pokes her head around the corner and says something like, "Is that my salad container ... my lamp!!!!!"
