redesign tank

[need help]

I have a 55gal. and not everything is going well. I just changed the water for the 3rd time in less than 10 days and stuff are still dying. My levels are good, ph 8.1 cal 480, nitrite, nitate, all good.

I am thinking of moving everything out and just re-doing the tank. I have store water "Nutri.Seawater. I am think about putting eveything in there for a 1/2 day until I redo the tank

any thoughts?

Well my mushroom are dying, the featherdusters are closing up and dying, snails are dying, the only thing living is the hermit crabs. And I am waiting for them to die..

Not going well.

What about temp and salinity?

have you tested ammonia? how long has the tank been setup. also, actual numbers are preferred. how much live rock and live sand or is it barebottom? more info of the tank would greatly help other reefers on here give suggestions.
