it does look intersting though, no ars-ing around with air pumps if you dont have an air pump, its even cheaper DIY
What heat source do you use, just a lamp? A special type or just a bedside lamp?
It must be a sign!!
I was only looking in the LFS this weekend at these make your own brine shrimp hatchery.
JBL seem to have lots of them> If i get the kids this then they might stop banging my tank shouting "NEMO NEMO" I havent even got any fish in their yet
