Help ID this algae

[surffer227]

I have this black algae starting to grow on my liverock. I've had an issue lately of a bacteria bloom since I accidentally over dosed some copepods and coincidentally my lionfish "Cecil" died of starvation the same night... All my corals have been closed the past few days and my tanks been cloudy, fish seem ok though. So any help or advise or an ID of this algae would be appreciated.

Anyone? I'm about to do a waterchange but I know that's not good with bacteria, but all my corals have been closed for days

what size tank do you have. how long has it been running. i do not see an algae problem. i am going to assume your tank is new. how many fish do you have in it. did you test your water yet if so what are the results

also i highly doubt your lionfish died of starvation. its a predatory fish. they can go a long time between feedings. also why are you dosing pods. none of the fish i see i the picture eats them
