Trying to diagnose between Flukes and Velvet

Hi guys, My newly set up 180g tank has struck some bad stuff. An overview of my tank:
Tank has been setup for about 2 months. I have about 150 lbs of cured live rock that I have been cyling for about 5 months. 100 lbs of dead finely crushed coral sand. I use NSW that I get from our local aquarium which is supposed to be filtered, and has no living organisms in it. I have been using this NSW in my 2 year old 75g sps dominated reef with no problems whatsoever. All fish in the 75g have always been healthy. The 180 has a Reeflo Orca 250, a turbo twist 12x UV sterilizer, Mag7 return and I am using 2 Modded Maxijet 1200s for circ. This 180g is supposed to be a FOWLR, and my intentions were to have multiple (3-5) large angels in the tank. When I set everything up, I tested the water for a month, and all params were in check, pH was stable, temp was stable, no amonia, nitrites, nitrates. I had a 5 inch Blue Angel and 5 inch Blueface angel in a qt holding tank for the past 3 months. I put those fish into the 180g. They were doing great. I then introduced a 8 inch imperator. For the first 2-3 days, it was eating everything in the tank. On the 3rd day, it stopped eating and was covered in what seemed like ich (white spots all over and eyes were slightly cloudy). I took it out and put it in a hospital tank treated with Furazone Green ( I know I was supposed to use Cupramine, but didn't have it at the time). Well, after a day in the Furazone green, I looked at the fish, and it was sliming, and the skin was slothing off. Well after another day, it didn't make it. I didn't stop there. I bought a 5 inch Passer Angel and put it in there with out qt'ing. After about 3 days in the tank, same thing, stopped eating, eye cloudy, started sliming then died. I added a Dragon wrasse into the tank, and it is completely healthy, always eating and no signs of disease. I have since removed the Blue angel and brought him back to the LFS. Right now, I have no fish in the tank. How do I know if I have flukes or velvet or something else. Symptoms for fish are:
-Skin sliming/slothing off
-cloudy eye
-white specks-looks like ich, but larger
-fast respirations
-not eating
-lying on their side=dead

So, what are my options. My plan is to leave the tank without fish for 2 months. Should I do this in addition to anything else. I do have hermit crabs, some starfishes, sun coral and some sponges in the tank at the moment. I have learned my leason from this ordeal and will QT from now on. I guess I was lucky because I never QT'd the fish in my 75g reef and everything is good wit that tank.

Is my substrate that I'm using going to be a problem in the future. I don't think it is arogonite, but finley crushed coral or is that the same thing...I don't know.
 
There could be a few different diseases going on at the same time

Velvet looks like a fine white sheen

Whereas ich looks like grains of salt.

The cloudy eye could be caused by flukes.

It's possible you had all 3 of the above.

If you leave the tank fishless for 8wks, then all 3 of the above will be hostless and should die. To be on the safe side, I'd keep it fishless for 3 months.
 
limitdown, thanks for the advice, I like your sig by the way, fish only is not any easier, though I thought it would be.

That's exactly what i thought when i started my 200g FO 1yr ago.

Since then I've lost $1,000+ in fish to velvet (in 5-days, my fault for not QT'ing), battled ich and flukes too many times and various bacterial infections. Compatibility and aggression are also big issues. I've had fish that were supposed to get along end up beating the heck out of each other. While I've had luck with fish that were not supposed to get along.
