rhodactis turning translucent

[sardonicscorpio]

I've had this tonga rhodactis about 2 weeks. It came from the bottom of a tank lit by 2x400w MH and 1 96w 10k PC. I have 1 96w 10k PC and 1 96w actinic. Tank is 65g. I had it on the top rock, about 10 inches from my light, medium flow. The last couple of days, its been getting sort of whitish and see thru, losing color and intensity. I moved it lower in the tank to a spot with broken shade, low flow. I thought it would be fine high in the tank since its used to brighter light. Any suggestions? The first pic is the shroom today, second pic is last week.
