3 day blackout... best decision ever!

I just finished a 3 day blackout with added peroxide and uv to fight a really agressive dino outbreak i completely wrapped my tank in cardboard and only turned on the lights for feeding 10 mins per day. Here are some before and after pics. My tank has never looked cleaner!
