In Japan, we simply just top off with tap water since the water is idealized for shrimp keeping.The key is just to keep the water parameter stable.
I top off my tank with pure RO but in a small amount every 2days so it won't disturb the shrimps. In addition, I use water conditioner to stabilize my parameter (black control).
I think everyone probably have their own method. I'd recommend test then adjust since the water source, substrate and filter system are different.

Where do I get RO?
TDS : total dissolved solids.
ppm : parts per million.
RO: reverse omosis.
I'm sure there are lot of topics about this if you do a little search in the forum.
