Help! All my fish are dying, but my corals seem normal

Well, it turns out i should have started with biospira.

I finally decided to just set up a secondary tank to at least save my fish. Set up a 20g long with 2 hydor 425 pumps, a spare heater, 60 gallon air pump and stone, 2 pieces of rock from the main tank, and 20lbs of live sand.

I figured even starting over with a really heavy bioload, my ammonia levels should be much easier to keep in check with water changes in a 20 gallon.

Initial: added prime
Hour 6: ammonia at .5, added Stability.
Hour 12: ammonia at 1, 25% wc, ammonia at .75, added prime
Hour 18: ammonia back up to 1, nitrites at 0, added biospira
Hour 24: ammonia still at 1, nitrites at 0.25, nitrates at 5
Hour 36: ammonia still at 1, nitrites at 0.5, added stability
Hour 48: ammonia at 0.5, nitrites at 0.25, nitrates at 10.

Main tank got a smaller dose of biospira gallon for gallon, but I've gotten everything i could save out and put it in the secondary tank. Ammonia levels are still off the chart.. like, tested water is almost black, not dark green, so im sure its around 12.

A very expensive lesson.

Hmm, this is interesting, just about 2 months ago now I moved about 4 hours away and had to move my 55g freshwater planted, my 20g freshwater planted, and my 75g reef tank. I used a 55g food grade barrel to transport 55g of old saltwater and I made a mini aquarium with half of my sand and live rock and all my fish in a igloo 55qt cooler. Suffered zero casualties even though I stirred up the sand like crazy. But literally all my old sand and rock was used in the new aquarium. Did I just get lucky or what? Should you normally replace substrate when you move?

Guy at my lfs tells me its probably because i was relying too much on my diamond goby and nassareus snails, and not vacuuming my gravel enough.
