Does anyone have any ideas on how to build a professional type brine shrimp hatching cone?
I have used soda bottles and water bottles and some eggs do hatch, but alot settle on the bottom and sides and are ruined, even with an air stone in the bottom of the bottle.
It is also a pain to suck start the siphon hose to fish them out.
I have seen lots of pro style brine shrimp hatching cones, but they run about $30 for the cheap ones, and $100 for more expensive! http://www.aquaticeco.com/index.cfm/...etail/iid/6057
If i could build something myself id like to try and save the money.
I have tried to find a plastic cone at craft stores and pet supply shops but cant find anything.
I thought maybe a large funnel, or maybe just a strait tube might work, but i need some ideas.
This picture gives you the basic ideas of how it is supposed to work.
