Outch !... If these readings are precise enough, You have liquid rock.
Try to have your LFS do these tests for you with liquid test.
If my eyes / monitor / brain, works good enough, You have a GH of over 300 ppm, KH around 180 and more, with a PH over 8.4...
"Very hard" in both sense, these levels push the limit for most of them. Maybe Sulawesi Shrimp could make it. If you turn your tank to brackish water.
Can you do this same test on your source water that has sit for a day, when you can. I want to be sure if your source matches and nothing is hardening your water in the tank.
But for the moment it will be difficult to have even the toughest freshwater shrimps on the planet.
