This is really cool. I'm thinking about trying it out.
Do I still need to let the water sit for 24 hours with the baking soda and salt before adding the eggs? I would use distilled water. I did this when I was a kid using a mason jar. I don't remember having to wait.
You can get more brine shrimp eggs than you can use for under $3 and some Artemia food for under $2. Of course, these aren't REAL Sea Monkeys. It would be interesting to see which tank does better.
