Perhaps the current shrimps gradually dying over an extended period of time could just be lack of certain minerals or nutrients in the water to support their continued growth and molting. Your new setup with the additional minerals and vitamins should help with this issue. Alternatively, you could also just carry on with your current setup and let the tank mature further, eventually the parameters should become balanced and conducive for the shrimps to thrive in.
For any new plants or hardscape that you purchase, it would be a good idea to soak and quarantine them for a while before introduction into your tank, sometimes they may still contain residual pesticides from the plant farm which might affect the shrimps
Do also check that no one in the household is using any chemical aerosols (ie. cleaning detergents, polishes, perfumes, deodorants etc) in the same room or around near the tank, as its possible some of those toxic chemicals could get into the tank and cause issues with the shrimps too.
If your main focus is keeping and breeding the shrimps, then its definitely best to use soil which are designed specifically for shrimp keeping, like the RAC soil. It will buffer the tank conditions for the shrimps without high levels of ammonia being released (the shrimps have no use for the ammonia anyways, they are not plants).
ADA aquasoil is mainly for those who focus more on growing plants, its not actually designed for shrimp keeping (though its still possible to use it for shrimps, just need extra time to cycle it and additional work to to flush out the excess unused ammonia and nutrients).
