Tank is Crashing - Pest Algae went sexual

[FBNitro]

I had a Pest Algae go sexual last night or this morning, I noticed the issue around 11am. The water was milky, very milky. Made me think of the water when you rinse a glass after drinking milk.

Anyhow, some background: The tank is 10 gallons, I've got about 18# of LR in it, it's been up for a year, I've got an AC110 that I've turned into a fuge. I've never lost a fish, but I've had a couple corals RTN. I have 2 gobies and a lawnmower blenny. I had a Skunk Cleaner shrimp (see below).

So this bad event happened, I already did a 30% water change (most I could do at the time). I've tossed in some carbon in an effort to clear up the water. So far, corals all look bad, the Hammer seems to be normalizing, my candy cane looks like it might not make it. My Skunk Cleaner shrimp died an hour ago. (first non-coral frag/snail I've ever lost)

What else do you guys suggest I do? I've got another couple gallons of salt water made up (made it today). Should I change it tonight, or wait until tomorrow?
