To correct the pH of tanks 1,4,5, add enough sodium bicarbonate to bring the pH to a neutral 7 or a little over as trout grow better in slightly alkaline water. This should not affect the Australian bass as they can tolerate water that is quite acidic to very alkaline.
Trout’s optimum pH levels can range from 6 to 8, but when the water is too acid the trout will not reproduce. Australian Bass are a hardy species of fish which can survive in acid levels ranging from 5 to 8. I would say that both fish survive well in neutral water.
The species of fish that is in the most danger is probably the Rainbow trout as the water is very acidic and the fish may not want to live and reproduce.
Replace 1\3 of the water with clean fresh water. This should bring the pH back down.
Murray cod prefer pH levels of 6 to 8 but their optimum level is 7.
Hell, Vaccination ... as well!
