With different versions of ADA Amazonia which is preferred for Caridina ?

[Purplepanda]

I have the option of getting a few bags of Amazonia Version 1 with older stock being released on the market here. Any thoughts please on which version of ADA Amazonia is preferred for Caridina or is it all sales talk and pretty much the same ?  I now have Amazonia Version 2 in several TB tanks, but still early days to tell. My LPS was told by the local ADA rep that Version 1 is more sought after by shrimp folk , is there any truth to this ? Given its scarcity its 50% more which sounds a bit nuts for older stock !  I also have Amazonia 2 in some tanks as opposed to Amazonia Version 2 and that did well, but ten years down the line I need to revamp things. I gather Amazonia Version 2 has less nutrients so hence a separate pack of tabs supplied for planted tanks. I would imagine less nutrients might be better for shrimp.  It also has slightly smaller granules than Version 1 which again I thought would be welcomed by  shrimp. This is all getting mighty confusing I have to say...
