Dinos

[Jaws]

I'm not 100% sure but I think I can see signs of the dinos coming back. I can't see any brown wavey snot-like substance but there is some dead looking grey snot-like substance. I have a feeling this is just the beginning of another outbreak.

Any idea what I can do to stop this before it starts?

How harmful would it be to the coral if I left the MH's off for another 5 days and just left the actinics on?
