It could be the PH maybe? Do you have anything in your tank to buffer the water? I find crushed coral substrate the best to use. What is your Nitrate levels?

0.0 nitrate/nitrite

Buffer used crashed seashell, seems it not enough. I have not crushed coral. Eggshell or turtle calcium are good substitute?

I'm not sure what turtle calcium is but eggshell will work, how old is your tank again?

If your snails are not having issues with their shells breaking down i don't think the PH is the issue with the young perishing, maybe the tank just isn't mature enough? What food do you use and how often do you feed?

No feed. Should I do it?

You can try, i feed my baby tank once a week but a VERY very small amount of spirulina powder, i get a medicine syringe and suck up tank water then push it out into a container and add my spirulina powder while mixing it then suck it up with the syringe and blow out the food under the waters surface.

That's a really good point, @Bat have you seen any dead babys?

No one live or dead, my friends. Disappeared. A lot of larvae, many young shrimps walking over the rocks... and few days later disappeared.
