I've just recently tried my hand at actively rearing fry so my experience compared to others on this site is very limited. With that in mind, there are a lot of knowledgeable folks on this site (like jetajockey for instance) so I'd heed their advice & ask as many questions as you can. BTW - Thanks jetajockey for your advice the other evening, it was really helpful.
However, hatching brine shrimp is pretty easy. NO special salt needed. All I use is regular table salt, not iodized salt, just plain. I use about 1 table spoon of salt per litre of water (I use 2 litre soda bottles as my hatcheries), & a pinch (however much I get in between my index finger & thumb) of baking soda to get the ph to 8 (this is an ideal ph for brine shrimp), & regular tap water.
A 1lb., 10oz "tin" of salt costs me about 50 cents & a 16 oz box of All purpose Baking soda runs me about another 60 cents at my local grocers. So making a hatching solution is fairly inexpensive.
I've never tried decapsulating my brine shrimp eggs. I've come to understand (just like you have) that they are higher in protein, are smaller & thus easier for fry to consume, & that since the cysts (egg shells) have been removed there is less likelihood that the fry will get empty cysts lodged in their digestive tracts which in turn will decrease mortality rates.
But even with all of the benefits associated with using decaped bbs I still haven't come around to doing it. And I may never bother with it myself, maybe because it seems like a bit more effort than is really absolutely necessary (perhaps time will change my mind). And after reading a lot of these posts, it seems like it's really up to you. Decaped or not, seems like your bbs will benefit either way
