Almost everything's dead for a third time

I have a 90 gallon that I set up, 2 years ago, I have a deep samd bed and tons of rock, a refugium that cannot seem to grow any macro, wet dry filter with pads and carbon, protein skimmer. It was stocked with everything that came with the tank when I bought it and some other fish I found from someone else breaking down a system. This was great for a year, then I added one keyhole tank that hid and died and then everything died, except one blue damsel. Months later and plenty of testing, I restocked...great for two weeks then everything died. Everything still tested ok so I added a yellow damsel, he lived for months at a time, even without food, refugium started breeding Copepoda like crazy, months went by and I just restocked again, new triggers, clowns, a tang...everyone was eating like crazy, but had a bicolor angel that only hid, he died, the clown trigger and tang looked like they were covered in white specks, so I moved everyone out into a tq tank I quickly made with half tank water half freshautolinker.com autolinking image saltautolinker.com autolinking image water. I dosed copper safe thinking it was ich, white spots gone, now clown trigger is dead, yellow damsel is dead, niger dead, tang covered in black blotches and looks like fins rotting off, almost dead.

It seems like my tank has some crazy parasite or bacterial disease living it it!

How do I nuke it? It's fish less now, just a bunch of snails, nasarius are a nj local on the bays!

Gallons of bleach?

I'm hoping my two maroons pull through, but what if they carry this disease back to the main tank?

Deep sand beds are nothing but trouble(I don't even want any sand in my tanks anymore).I would consider removing a whole bunch of it if there are no fish in tank as I'm sure sure you'll stir up some anerobic bacteria(deadly and definately in your sand bed).
Do you have lighting over your fuge to grow the macro?It doesn't even need a particular light like the tank.any form of flourescent should work.24/7 for the fuge.
almost any disease in saltwaterautolinker.com autolinking image can be eliminated with hyposalinty so if the tank is without "precious" life lower your salinity.I would reccommend this also for your QT tank.

Thank RM if he is ever on as I found this link from him on another forum in 2011.

Re: Almost everything's dead for a third time

Ok, this is the way I see it. Your Macro won't grow because your Deep Sand Bed is eating out all the Nitrates that are needed to grow the algae out. In other words your water is to clean. You also need to have phosphates to grow it out, not alot mind you, using a Hanna Checker will probably test out at like .05 or slightly above, but some is needed. Using the some light on the Fuge will also help, gotta have something, or no photosynthesis will occur, and it dies out.
Your fish goin dead on you the last time, was a severe out break of MARINE ICH, so not much you could have done there but put the fish into HYPO right away to kill off the parasite. WIth this action going on, your going to have to wait 8 weeks to add anything to the tank at this point. Now, you can add fish after that time frame. But I caution you, ICH is something that can be brought in by any fish, whether it visibly has it when you buy it or not, its still a possibility.
But, theres still hope, knowing what was in your tank is half the battle. Im with CoralBandit on Deep Sand Beds, the older they get, the more volatile they can become, and need replaced. I'd also get rid if or myself, but thats just my opinion. While you have no fish, its an option.
Black blotches could have been HLLE, and could also be fatal.
