Coralline Algae turned white

[90gallon]

Recently I completely emptied my 90 Gallon corner aquarium to replace the stand and then filled it up with fresh saltwater. I did it all in one day but now I have noticed that the coralline algae has turned white. Why is this and is it bad? I have tested the water parameters and everything has checked out. Right now the only thing in there is the live rock. Before emptying the aquarium I had it set up for about 2yrs.

putting new water i think your tank needs to be cycled again. which might kill off the coraline. wait till one of these pros answer you just to confirm

It's just bleaching, did you change the lighting? It will grow back.

It will do that when you place it in a new envionment weather it`s chemical or lighting. As Scott said it will grow back and with a vengence.

No. Very little of the bacteria live in the water.

Agree with others - coralline doesn't need to be out of the water for very long to turn white.
