hello all! I'm a newbie with a 90 gal tank... I bought my tank already set up with fish, live rock, and some corals like mushrooms and leather heads. The previous owner quit caring for it so I'd like to say I'm trying to "bring it back". I bought a refractometer and tested my water earlier today and the salinity is pretty high at 1.028 and my PH is crazy at like 9.2 I know a move can be extremely difficult on a tank and from what I have read it basically has to establish itself again. It also appears some of my corals got extremely stressed during the move and have died causing the Cobb web looking stuff. Any suggestions to get my numbers down? I'm guessing possibly a good water change? Any help is appreciated, Thanks!
