Artemia Cultivation Units

I haven't seen them up close but from what I understand those are they types of things that will allow for larger hatches. I have seen some large conical bottomed containers in the Aquatic Eco Systems catalog

I think the 90,000 dollar price is wrong though (look at the 3+ price, I'm guessing they missed a decimal...). That shape even looks like it could be done DIY style...

For somewhere in between... I have used flower vases before... Michaels craft store sells some interesting shapes in the 5-15 dollar range
