how big is your container?
for me I used a 1.5L soda bottle cut the bottom and bubble with 3- 5 teaspoons of salt.
it hatched at around 20 hours.
where did you get your brine shrimp eggs?
I tried hatching brine shrimp with 1 tablespoon salt, medium tamk, and airpump, after 20hrs still dont see any brine shrimp.
What could be wrong?
Thanks

I bought it from a LFS. How do you filter brine shrimp from the eggs?
siphon out the bbs onto a net...
hatched eggs will float and bbs will normally stay at the bottom.

I've created this instruction in another forum, do take a look..

try with 4 full spoon of rock salt, using those take aways plastic spoon,
the salt you add is too less.
CHeers..
I'm using this for the past 6 months.... https://reefbuilders.com/2009/11/12/...-moving-parts/
Available at Fresh & Marine.
Quite easy to hatch. Just put water & eggs. They will hatch within 24 hours & swim to the center.
No air bubble or siphoning needed.
For best result, use marine salt.
If used marine salt, the hatched water can be recycle for few cycle to save cost.

I've seen that hatchery system online before, very interesting design. I'm also keen on this simpler technique too. But without aeration, does it still generate decent hatch rates? And which brand of brine shrimp eggs do you use with it?Originally Posted by Suzerolt
Reason why i ask is because my own experience trying to hatch BBS in a shallow container with no aeration yielded relatively low hatch rates (compared to the conventional aerated method), so i'm not sure if it's due to the quality of the eggs i use or how i performed the method.
Sorry to high jack the thread, but could I use rock salt to hatch Brine shrimp?
If so how much would I need to put in a 3 gallon tank

3 gallon of water is too much, would suggest using hydrometer to measure the salt salinity.
BTW you are hatching for large quantity ?
another best way is to get direct sea water.
CHeers..
the way i measure hatch rate is i use 1 flat plastic spoon of bbs to hatch, after 24hrs harvest, i would usually got 2 and half spoon flat of hatch bbs.
use the inverted plastic bottle method with big aeration for best result and ease harvesting. for this i top up with 2 full plastic spoon of marine salt, can reuse the solution for a week for hatching 1 spoon of bbs using those fast food coffee stirrers,
CHeers..
can use rock salt to hatch bbs.
CHeers..
can just use normal aquarium salt to hatch, reasonably cost.
do note that the quality of the eggs also play a part, together with the temperature. Some say need to use warm light or sunlight. while some do not.
there is another kind of BS that does not need any aeration or salt. It is called the fresh water fairy shrimps. just put them in the water and wait for them to hatch. BS is also a kind of fairy shrimps
I bought $1.50 big pack of salt from Shin Sheong for hatching of BBS and for human consumption..
Can shin sheong salt be used to treat fish disease too?
Depends on the type of salt, can check the ingredients. Normal table salt usually contains iodine and anti-caking agents... so may not be suitable for certain sensitive livestock.
I guess you can try and see, if the livestock are okay then it means they they can probably tolerate those additives. If not, then better to use aquarium salt or any other salt that doesn't include extra stuff.

I think that hatch rate is mostly dependent on the quality & age of the brine shrimp eggs.
I got some eggs from a fellow forumer. I understand the source was from ebay / Thailand. Using this small scoop.....
From the scoop, able to get this amount within 24 hours :
I thought it was pretty decent, considering the convenience.
I did notice that hatch rate decreased as the brine shrimp eggs aged. It was quite good in the 1st 6 months. And started to deteriorate after that. Hence, i'd suggest buying small amount of eggs each time
For salt, i use marine salt (eg. Skimz, H2 Ocean) at 1.025 using a refractometer
Thanks for the info!
Will get the hatchery and try it out... looks like a simpler alternative to the aeration methods that i currently use to hatch my BBS, especially for harvesting smaller quantities at a time (its ability to auto-separate the shells is a big bonus too).
I did not try on fishes but I think should be fine because the BBS are ok.. get the cheaper salt, more expensive means more things added. also like what UA has mentioned, see what is the ingredients inside, look for no iodine . will try to take a picture of it when I get home..
