Please help ID and suggest a way to get rid of this stuff. It looks terrible and seems to be bothering corals. The zoos don't want to open with this stuff covering them. Is slimy looking. I don't see bubbles trapped underneath it. I vacuum it out and blow it off the rocks and is back within hours.

Looks like diatoms. Increase flow and run a lil phosguard will help pull silicates out of water. How old is the tank?
