I guess my last question would be hyposalinity ?

Sure, running a specific gravity of 1.009 works well for ich and also manages many species of flukes. It won’t help with velvet or Uronema.
Here is my post on that:

So here is the blue hippo from this morning till this evening. Doesn’t even look like the same fish. Breathing has become rapid. Tried a 5 min fresh dip to give her some relief and the second pic is what she looks like now. The puffer just started seizing and finally died. Now the coral beauty is covered in spots and most of the fish have started to scratch on the sand. Copper is at 2.44
