I'm using the same blue two netting to filter. Firstly, it depends on the size of Bbs eggs. I have 2 kinds of Bbs eggs. Bbs egg 1 is smaller than Bbs egg 2. Bbs hatched egg shells tend to slip through the filter net. Bbs Unhatched eggs 1 seldom slip through. My Bbs egg 2 is bigger in size. Less than 1% slip through. Bigger Bbs. Non stick eggs shell.

Thus, it sometimes depends on Bbs eggs also.

I got mine from Brine Shrimps Direct the 80% hatch rate stock. Plenty of newly hatched baby brine shrimps within 18 - 24 hours.

once again thanks all for the input (: i am learning as the days go by.

Guess I was having the same issue previously.
I used my kept (unused) bbs I bought 6 years ago. Kept in a drawer.
Nothing hatched after 3 days. Tried twice. Both failures.
Went out to buy ocean free bbs 9g for 8 bucks.
Bloody expensive. It says 95 and above hatching rate.
Tried, the same thing happened. I even changed the salt to fine premium sea salt (100%) fit for human consumption. Also failed.
Then I got bbs from Tarzan, he claimed sure will hatch.
Well, sure enough it hatches within 16 hours. By 20 hours I think all hatched.
Been feeding daily now. Only thing is I have only one hatchery that I bought from another member. Looking for another one that is similar. Really small and compact type. If anyone knows where to get (beside taobao) please let me know. Cheers.

hatchery?any pics to show?it's easy to make.....no need to buy bah?

My recent experience is to play around with amount of salt.

Around 25-30 gram of salt for 1 litre of water seems to be good start.

For one source of bbs, I tried 50 gram of salt of 1 litre, then 24 hours of hatching is not good enough, it requires 48 hours of hatching. Then change it to 25 gram of salt for 1 litre of water, 24 hours is good enough.

Cheers

I only played around with different salt content, salinity, when I used 70% or 80% hatchrate bbs long time ago. Nowadays, I don't need to vary the salinity because I use 90% hatchrate bbs.
