You have to be sure you're using clean tools, that you're using tools which protect shrimp from being sucked up.

On water changes, make sure they're the same parameters, or you'll be killing off shrimp.

On top offs, only use RO

Did you use prime when you added the new water? I have heard that when using prime it can mask the nitrates when tested. Been a while since I tested my water as everything is stable but it could be something. When you replaced the water did it stir up the substrate? Otherwise I am at a loss as well to what the problem could be.

you bred them in ro/tap mixed water. you did a w/c of only tap affected the offspring. die off is going to happen or you didn't condition with prime. its one or the other.

You've replied what must've caused the massive baby deaths.
The week you see new babies try not to avoid a water change coz a slight change in water parameters can cause deaths esp.in baby shrimp! Take into consideration u did not change water for 2 weeks, when u returned home immediately changed water this time tap water only also. U've mentioned u do not use declorinator.
May be your municipality added some kind chemical or extra chlorine to improve water quality which caused a sudden change in yr tank water parameters which lead to massive baby deaths. If copper had entered yr tank then u would've seen adult shrimp deaths too so copper is not the culprit

i would say your tap water was just to different than the tank water. if your not useing a dechlore then that is most likely the cause. the gh or kh could have been off as well as the ph. temp might do it too.

100% water change is the problem. Baby shrimps are sensitive to water change. I don't even do water change when clutch of babies just came out. Only top offs and 10% water change if nitrate is going up to 20ppm.
