No coralline. This was and will be for a while yet a FOWLR the lights were the wrong spectrum and low wattage
Acclimation help needed

I'm surprised the rock and fish were being kept at 1.009. That's hypo salinity. I have doubts there's much left on the live rock except bacteria, those are hard to kill. It's gonna take some time to safely bring the salinity up to NSW levels.
Was the previous owner treating for ich or some other disease?

It is just white/brown rock with bacteria? The low salinity is still stressful, but probably OK.

Yeah mostly brown

You can't really acclimate fish to 1.026 from 1.009 without significant stress or death unless you take a week or so . I'd set up a small tank at 1.009 for the fish and bring it up slowly ,.001 per day . Consider the time used in this proces as a a quarantine period which should be done for new specimens anyway.

What are your ammonia levels? I'm thinking your nitrifying bacteria is probably in bad shape and the tank needs to be cycled. Being that you had such low salinity all the bacteria probably died or is dying

Since the rock has been in 1.009 sg for sometime, I suspect most marine organisms are gone;not sure many have a tolerance for sg at that level;some might;some strains of cryptocaryon irritans(ich) do, for example.
Unlike fish, invertebrates can't osmoregulate ; their internal sg is heavily dependent on the water around them ; they are isotonic .Though some may have a broad range of tolerance, I suspect most will suffer a loss of homeostasis and die at 1.009sg.Cysts,eggs and spores may still be viable though.
Ammonia oxidizing bacteria(nitrifiers ) ,however, do well in hyposalinity. There may be some temporary suppression in their activity with large and rapid changes in sg up or down but they multiply quickly and mutate to adjust to changing conditions; so, I think you will still have a viable amount of ammonia oxidation but it's worth checking ammonia levels and having some ammonia detoxifier on hand just in case.
