Emergency! Need help!

So I have a thread going about treating ich:

Looks like Herbtana (I used 75% of the recommended treatment to be safe) completely crashed my tank. Everybody looked happy yesterday, but when I came home tonight I found 1 lyretail anthia in the anemone, 2 others dead in a cave. I grab them out.. then I noticed my strongest and meanest fish that was in my sump.. dead (yellow tail damsel)

I noticed my lawnmower blenny is stressed, he later dies. My biggest anthia that was just turning into a male.. dies. My dogface puffer at one point, does into a cave puffs up to wedge himself and all of the sudden it looks like he was trying to close his eyes.. WTF!

So all in all.. very stressful night. I only had about 15gallons in water prepped, I changed the water. My skimmer is so out of wack from the meds, it just bubbles over. I took the skimmer out and put it into my fish room sink, and it runs fine on tap water (i can adjust the water level)

Oh, and my kole tang looks like his face is melting off.. I have NO idea whats going on. The UV sterilizer I bought from Golds died, there was water in the compartment where it holds the UV bulb. I rushed to Golds and they replaced the bulb. If the bulb shorted out in the tank, could that have caused all this die off? They sold me a couple of nutrifin cycle and prime, and I rush home.

I added the prime and cycle into the water I had prepped.

Sorry if this might sound bad (grammar wise) just tired, and have no idea what to do.

P.S. I don't have a QT tank. However, 2 weeks ago, I took all my old LR from my office tank and scrubbed them. The tank still has all the LR, heater and powerhead running. It only has 40% water in the tank though (lots of rocks and very little swimming room). The remaining fish seem fine but you never know.

Actually, the remaining fish are kind of begging for food.

I have another trash bin filled with a combination of RO water and tap water (combined them to get the water mixed ASAP) mixing with salt. I am hoping to do another water change in the morning.

Any help is greatly appreciated.
