Also if it was a lack of aeration we'd expect a pH on the higher end. Do you remeber what it tested op?

If you were having low oxygen, the fish will try to pass more water over their gills to get O2. The fishes gill plates are generally beating rapidly, often with the fish breathing at the water surface where O2 exchange is higher.
If you think there is a "toxin" in the new gravel or live rock you might want to filter the tank with carbon or Poly Filter.
I assume that the tank salinity is good.
What behavior or characteristic are you describing when you say the clown isnt "looking good?"
It's been over a month and a half since the move - this started 6 days ago - lost 0 fish until more than a month went by then suddenly 1 fish a day for 5 days. No sign of ick or anything visible.
I do think I have seen the fish breathing rapidly. I do have carbon and a poly filter in then tank. I put the poly filter in today. The clown looks a little discolored and his fins aren't as perfect as they were yesterday - maybe breathing hard too.
Ditto, I want to know what the symptomos before death are. I doubt the o2 idea as I would assume the fish would crowd the surface around the same times as ive seen when I bring larger numbers of Livebearers home in a bag. Usually when fish die in succession that fast I think very aggresive internal parasites or fungus, but the fungus would also be visible.

Ph is in-line.
If it is low O2 they should recover very quickly. Also, Low O2 generally takes out the largest fish first.
Discoloration sounds more like a disease of the skin. Surface parasites or bacteria can cause discoloration, and they can interrupt gill functioning and make the fish breath faster the same as low O2 would. I hope this is not the case. GL
Symptoms are - i - porcupine puffer got cloudy eyes and then rested on the floor the next day, later that day wouldn't move. dog faced puffer was laying on the floor a lot more than usual and then was upside down the next day, the yellow tang was also laying flat on the sand in the morning (night before swimming, eating, looking normal) - the tang looked to be breathing hard for a while....the clown right now appears a little discolored, fins frayed a little bit, swimming, maybe breathing a little hard. the last fish, a sail fin tang looks fine and swimming around (not problem so far)
With all due respect, and I don’t mean to offend anybody, but you guys are shooting down the idea of low oxygen without having any facts. Literally zero facts. I’m not saying It is 100% a oxygen deficiency, But to steer him away from the possibility of it being a oxygen deficiency without even knowing the symptoms of the fish before death, will do more harm then good, And ultimately we need more facts
How do you know the fish was not gasping for air? Also, the fish won’t necessarily die in a couple days, no matter what there will still be some oxygen injected into his water column from the overflow, which could be enough to sustain the fish for weeks. Think of it this way as a analogy, if you had a hourglass completely full of sand which was running out, and you kept adding teaspoons of sand to keep it going, it would Stay full longer, but would eventually run out. This is the same with oxygen in the water column. The tank could have had plenty to begin with, but slowly depleted until the fish died.
So biggest fish died first... I’m still leaning towards a o2 Deficiency, and if that’s the case it will be easily fixed. Put your powerheads right at the waterline and make a massive air storm for a couple minutes inside your tank, then lower the powerhead enough to where it doesn’t make as many bubbles. If it’s a oxygen deficiency, you will see almost immediate results (12-24hrs). It’s a very easy task to do in order to rule out a oxygen deficiency, Then you could move onto the bigger possibilities like parasites, which may also be the case but we need more information.
what have you done to the tank in the last 6 weeks before your first fish died? Did you add any new fish? Change any filtration ? Added any chemicals ? Do you use scripps water or mix your own?where do you get your top off water, Do you have a rodi filter ? What food do you feed your fish?

I also think its a disease of some sort, perhaps bacterial infection. The symptoms youre describing (popeye, fins rot, rapid creathing) point to that, although discoloration and rapid breating can also mean velvet. LivinLocal asked some relevant questions that would likely confirm this.
If you added anything new to the tank (fish, coral), they couldve brought something in.
Beneficial bacteria which is needed for a cycle lives on actual surfaces (rocks, filter media, etc), not on water. That said, Im sure it doesnt hurt, I just dont think it helps with a cycle all that much, if any at all.
Either way, I dont think its relevant here since the OP said they tested water everyday and didnt see any ammonia.
