I'm gonna have to suggest you stop using ocean water, there could be toxins or bacteria near the shore that you're adding to the tank and not testing for. Do you test your salinity? Myself, I'd do like a 50% water change using saltwater I made from a mix and RO water to start off with. Hopefully things havn't leached into your rock?
Your coralline algae is pretty intense. That dark purple looks amazing but may indicate you have really high levels of calcium in the water as that's what feeds coralline.
If you start using something like instant ocean salt and RO water during water changes you may find you've fixed the problem...
