Anyone have tips for hatching BBS?

    I can't seem to get it right. I'm not sure what I'm doing wrong, but I've tried 3 different methods and can only obtain the typical color change from brown to light orange. I get nothing beyond that, none of the eggs actually hatch. Anyone have a foolproof method that works every time for them?

    The eggs I have are San Francisco Bay Brand, the 6g vial. I've been using a very small amount of baking soda to stabilize the pH, and Morton's brand Canning and Pickling salt. My tap water is neutral and relatively soft (~1-3 GH/KH).

    I ordered some of the "Premium Grade A" eggs with the seahorse on the front to try but they won't be delivered for a few days at the earliest. Any help would be appreciated!

    I hatch bbs daily. I use Great Salt Lake eggs (Brine Shrimp Direct Bargain because they are less expensive). I use synthetic sea salt set to ~1.024 on a simple hydrometer. Question: do you dechlorinate your hatch water before you use it?

    I hadn't been, but the last time I did just to rule it out. It didn't affect a change in my results. The different methods I'd read through previously said dechlorinating was unnecessary due to offgassing.

    What hydrometer do you use? One of those slender glass hydrometer/thermometer combos? My hatchery is made out of a liter water bottle and all the other ones I see look way to big to submerse.

    First, if your tap water uses chloramines then the chlorine will not 'out-gas'. Brine shrimp are no different than fish in this regard. I use 2 litre bottles - the same ones I've used for 20 years - without a problem. I use an inexpensive (Sea-chem) plastic box-type hydrometer. Readings are close enough for hatching purposes. Also I never keep more than a month's eggs at room temperature. The rest I keep in the freezer in a tightly sealed container. Before opening the container for more eggs, I let it come to room temperature just to be sure that excess moisture from condensation doesn't affect the eggs.

    I'll try out some of your suggestions with the new batch I have coming.

    I'll have to recheck my municipal water website to see if it states specifically whether they use chlorine or chloramines. I believe SeaChem Prime neutralizes both, correct?

    Yes, it does. I use it.

    I tried your suggestions and actually had a fair number of BBS hatch out the most recent instance. Still very poor hatch rate, I'd say somewhere around 25-30% but no more than that. I also changed my light source out, as the water had been very warm, perhaps too warm (felt much higher than 86F)

    I think my biggest issue however is my eggs, since my eggs were not stored properly. After doing a bit of research, I realized I had been unaware (or ignorant/both) to the correct method. Won't make that mistake again! I'll report back when I have had a chance to hatch a batch from the new eggs I ordered.
