I cooked my tank a couple years ago when a fish splashed the bulb and it cracked. I have no idea how long the bulb remained on for but I only discovered the reason the tank was looking so weird when I found a piece of glass sitting on one of the rocks. I had no idea the bulbs could still run while being "broken". I ended up losing 2 or 3 fish to severe UV exposure and pretty much one side of the tank. The rock was bleached white as well. It was an eerie look. I didn't have much LPS and what I had was at the bottom of the tank and "less" exposed so there was not much bleaching for them. I lost all the SPS but some of the SPS undersides survived so I left them in the tank. The tank did have a slightly cloudy look to it but it wasn't milky. I would imagine that if you had both zoas and LPS "spewing" they would have attributed to the milky look.

I currently have glass on my lumenarc reflectors (they're designed to hold glass the same as the double ended ones) and will always have glass from now on. I lost a 7 year old scopas tang and a 2 year old powder blue tang that I nursed back to health (fish store rescue, stupid I know) and it was just too traumatic. Of course the fish that did the damage is a big stupidhead and hid in the rocks for most of the time the other fish were swimming around getting hugely irradiated. He continues to splash the reflectors and I can see just how much showing on the glass which makes me happy I got them.

No doubt water changes and carbon are in order, regardless. I'd hold off on the maracyn treatments until you have things stabilized. Did any of the cyano die at least?
