Algae Turf Scrubber (ATS)

Sounds like the heat from the bulb warped the plastic.

Possible, but by the way I had the screen hanging diagonally, the light was sitting furthest away from the back panel, and no light was directly hitting it. All the other panels were fine.

Odd.

wierd, any other heat source? can't see any other reason for plastic warping
