Thank you! I will find some and add to my tank. I will give an update in about a weekYou can add KH generator crystals, or add some buffering rocks, crushed coral in the filter. Add a little test in a week, add a bit more etc until you get a stabilised increase. Don’t add all at once or the shrimp will die.
I think I need to do it too now, my KH generator crystals are not enough and my basalt river boulders are not buffering as much as they used toThank you! I will find some and add to my tank. I will give an update in about a week

Cheapest option is limestone rocks from the garden supplier.
