whats happened to hkgar's screen is not common at all in my opinion.
I've never had a screen, or seen another screen go off like that.
It looks like it was cleaned and put back into the scrubber under full lights without waterflow. Its exactly how screens look when their no longer used & left in the sun for days. The remaining algae dies & turns to yellow gunk.
hgar's screen has two large areas that look like photo-inhibition has occured, while the top & the bottom are healthy.
