Choose a shrimp-appropriate mix
Remineralizers differ: some primarily raise GH, while others affect both GH and KH. Select a product suited to Neocaridina and your tank's substrate and water plan.
Use clean measuring tools and the label's dose for a measured volume. TDS alone cannot confirm which minerals were added.
Make each batch consistent
Dissolve minerals fully in a separate container, then test GH and KH before adding the water. Keep a written note of the amount and final readings.
Avoid changing the recipe midstream or correcting the display tank by guesswork. If a batch differs, adjust it before use and transition existing shrimp gradually.
For your own tank
Use one measured batch as a reference and record the product amount alongside GH and KH. That gives you a repeatable baseline. If results vary, check the measuring tool, dissolution time, and water volume before adjusting the display aquarium.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
