OK as promised a step by step as to how I decapsulate brine shrimp eggs. I don't know if its right or wrong but it does work and my fish seem to love them with no ill effects thus far.
1. I gather all my equipment next to a sink as this does require some water to rinse and drain things into.
the 2 bottles on the right, the big one is filled with salt water that I mix for water changes and the little one is just plain ole RO/DI water, not sure if RO/DI is really necessary but I always have some on hand so I use it for rehydrating and the final rinse. Also present are an Air pump, 20 CC syringe, K-cup reusable coffee filter, Clorox, a store bought brine shrimp hatchery and a simple home-made hatchery.
2. The first step I do is rehydrating the eggs. I use my little hatchery for most of this process because since my tank is little I don't need a huge quantity of eggs. I measure out 1/8th of a teaspoon of eggs and put it in the hatchery with RO/DI water. I let this bubble using the air pump for anywhere from 10 minutes to 1/2 hour depending on what I am doing at the time. I do occasionally stir it to keep all the eggs I the water as they like to rise and stick to the sides of the container out of the water.
After about a half hour I take the eggs and strain them through the coffee filter. Notice how the eggs are kinda a brownish color at this time.
3. At This point I pour a little bleach into the little home-made hatchery. Using the 20 CC syringe I then squirt the eggs out of the coffee filter into the hatchery. I get as many as I can out and start the clock. I once again drop the airline into the hatchery and let them bubble for about 5 minutes. The eggs will turn from that brown color to a bright orange. This can be from 3-5 minutes but I never go over 5 minutes. The orange color is what you are looking for.
4. At this point I once again pour them into the k-cup coffee filter and rinse thoroughly using tap water. I rinse until I no longer smell the bleach and then usually a little longer just to make sure. I then give 1 final rinse with RO/DI water.
5. I then transfer the eggs into the main hatchery using saltwater this time (I use the same mix that goes into my tank for water changes). I put a small light in them that runs 16 hours on and 8 off (only because its on the same timer as my phyto). I bubble them at a pretty good rate (Enough to keep the eggs from sticking to the side of the bottle). For the first few hours if I can I stir them occasionally also. seems like this is the worst time for them to want to kinda clump up and stick to the side. After that I turn the air down to a lower flow. as to not injure the baby brine.
From here I wait about 24 hours and start harvesting baby brine. For my little tank this nets me 2 feedings over the course of 2 days. Using a turkey baster I suck out about half of the baby brine and strain them through a brine shrimp net, then scoop up some adult brine from my other tank add them directly to my DT and the fish go nuts. 24 hours later I do the same thing again and start the whole process of decapsulating over. On the second day I also feed a pinch of pellet or frozen Mysis (depending on what I feel like doing at the moment) just to make sure the fish are getting enough nutrition. They seem to be fat and happy so it must be working.
