These stones have been tested, and do not affect PH. There is a test you can perform. The substrate is Tahitian Moon sand. I am lowering the PH using RO water. Once it is complete, I should have a PH of around 6.4 give or take a degree.
I got them from a local specialty shop. She is calling them “angel licorice gourami”, so no help there. I have 4 P. Nagyi coming next week! Not for this tank. Thanks for all of your help Helene. 🙂
