bleached acro with ati sunpower

[Spiny]

So, I bleached a bunch of frags (acropora) with my new fixture: sunpower 6x39w on a 36"x24"x16" shallow tank. The fixture was too close to the waterline.

How high should I put the fixture to let my frags recover? I moved it up so that the frags are about 28 inches below the fixture. Will that be enough?

You could also reduce the time the lights are on..... or put several layers of window screen over the tank and remove one layer at a time over the period of a few weeks
