the UVC got nothing to do w/ the death of some of your BBs bro.
I believe that some of your BBs died, during that two hours when you turned off your sump filtration system. Even if you turn on your air pump....it was on your last compartment ......and the water is only affecting the bbs on that compartment (and nearby compartment).....and not the rest of the compartments. The water is not flowing all thru-out the comparments....therefore not all water in each compartment is oxygenized.
just my 2 cents.
