You want a KH of 0-1 with crystal shrimp, and if you have the correct substrate, the substrate should be consuming the KH in the water and buffering the pH to the required amount for crystals.
That said, using tap water with KH in it can burn out your substrate a lot faster than using remineralized RO.
My recommendation is to buy RO water or an RO unit (as cheap as $65 on Amazon). RO water should be 28-50 cents a gallon, depending on where you purchase it.
Then get a product like SL Aqua Blue Wizard, Salty Shrimp Bee Shrimp GH+, Lowkeys GH Mineral Balance, etc. You have a choice between liquid or powder remineralizers, but be sure to choose a GH only product. Add the mineralizer to RO until you get about a 6 GH, then use this water as your water changes. Doing it this way will slowly increase the GH and allow the shrimp to survive better.
If you get a product that contains a KH booster as well, then it will be a waste as your substrate would consume the KH and exhaust it, thus would lower it's buffering capacities quicker than using a GH only product.
