For instance, I'm adding Salty Shrimp GH/KH+ and baking soda to DI water to reach a target of 6 dGH, 5 dKH. Those numbers are within parameters for snails, yet there's a good deal of shell erosion lately.
Most are various nerite species; there are also a chopstick and a golden mystery snail. All are affected to one extent or another. The supplier doesn't even list GH values, just KH.
Most suppliers are thoroughly confused about kh/gh.
Nerites need more gh. Bump it up to atleast 8, but probably need more like 10 or greater, and see what happens. Nerites can handle gh in the upper 20's
You can't define ph by gh/kh alone. You must first measure the ph. Then, you can estimate what the CHANGE IN ph will be after adding gh/kh.
Ph itself is a base, or central measurement in the first place if that makes sense. It is the measure of alkalinity or acidity which changes depending on more factors than just gh/kh. Gh/kh are secondary measurements at best.
I'd argue that kh/gh are primary measurements and pH is a secondary measurement. [emoji846]
Focusing on pH measurement alone nets you nothing. Knowing your kh/ gh values, your base, then allows you to understand better what the pH measurement is saying.
I’ll float these by you as food for thought. Maybe it’s not Ca, Mg or even Fe your short on and might be the cause of the erosion your seeing not the actual PH.

Salty Shrimp Gh+ will do the trick. If course so will Equilibrium and Nilocg makes a Gh booster as well. Or you could get your own dry Ca and Mg and mix your own (that's what I do, ~2:1 ratio).
Those all will raise gh without affecting kh.
Just go slow. Since you have shrimp, 1 dGh increase every week. The Blue tigers will be hardest to deal with. I don't have any personal experience with them but have seen 10 dGh as doable.
But see what 8dGh does for you first. That may do the trick? Although nerites really do like harder water.
