So, if you stick them in distilled water, you get little creatures to inspect. That's cool, educational, etc. I'm all for that. However, let me tell you why you want to buy these: These are THE KEY to clear water in a no-tech (no filter, specifically) aquarium. Here's an approximate timeline: Day 1) Here we go! Day 2) No change. Day 3) No change. ... Day 6) I guess that's a /little/ better. I guess. Day 7) Eh, ok, so I wasn't imagining it. It's a tiny bit better. I can see them moving around near the glass. Day 8) No change. ... Day 14) Well, I guess that's not getting any better than that. Better find an algae removal chemical that won't kill my snail. Day 15) HOLY COW I CAN SEE EVERYTHING!!!!!! I didn't even get to buy a chemical treatment. It's been a month and a half and I've had no clarity issues at all. I didn't even bother with the hatching instructions, just dumped them into my 1gal tank. If you want a little desk aquarium, get yourself some plants, get yourself some snails and/or shrimp, and BUY THESE. BUY THEM NOW. :)Read full review

It's been just under a week since I started the eggs. I didn't have a lamp, as the instructions request, but I set them in a very warm, sunny window. I see at least a few daphnia, some seed shrimp, and what I can guess will be rotifers, Most of them are still specks, but they're definitely swimming about, and there area lot of them! I've tried hatching water fleas only from a few different companies, and the hatch rate on these guys is much better compared to the other ones I've tried. Just in time, too, because one of my Endler guppies had fry the day after I brought her home!

I wasn't sure about these eggs, since they hadn't hatched by day 5, but then I moved them to my radiator and the whole thing burst into life! I'm really just in it for the daphnia, but I can't wait to see what else pops up. While light and water quality are clearly important, the big trigger was definitely heat. Don't neglect to warm the pool with an incandescent bulb or other source, or you probably won't see results. My lamp is LED, so the culture didn't exceed 68 degrees or so without a kick from the radiator. I greatly appreciated the detailed instructions and little pack of spirulina, even though I already had my own. Can't wait to get a big colony rolling so I can feed my fry!

USE PURE WATER! Can't stress that enough. I used reverse osmosis filtered water and 3 days later, I had some daphnia. I've been feeding them the spirulina that came with the package and they are multiplying like crazy! Shipping was very fast too. This product worked a lot better than others I've bought. I am going to buy a few more packs right after i finish writing this. If you want daphnia, this will work for you!

Don’t forget that they are tiny babies and are very easy to miss. Just follow the instructions and everything will be fine. I used RO water and a Betta heater to keep it warm. The heater is on for a few hours. I started them in a 1 gallon jar.
