That is true, but I still caution against it. This method of using aragonite or dolomite or crushed coral will raise pH but not GH or KH. Neale Monks and I went into buffering, and he said it is not safe to attempt buffering with these substances. Without getting into all the details, the issue I had with my barbs was unique, and this was only one aspect we considered in finding the root problem.
I agree shrimp usually need mineral, but I have heard there are some where this is less necessary. I had two clear-looking shrimp that happened to arrive in the bag with pygmy cories, so I put them in the same tank, and they did live for months in very soft pH 5 water. I had no other option, and I thought something would eat them anyway, but they were still there for several months. Don't know what shrimp.
But if sensitive fish like Boraras species are intended, I would not mess around with adding any mineral that they do not appreciate. Move the shrimp before messing with the Boraras environment would be my thinking.
