Help!! And suggestions

To make a long story short my father was in for a visit and decided to help out out while I was at work and clean one of my tanks (he's had tanks in the past). Anyway, that didn't work out well and he accidentally nuked my tank. It's been a disaster, things are dying left and right. Fortunately I only had two fish, and they seem to be doing fine. Not the same for everything else, however.

Basically everything is dead. Thankfully this wasn't my reef tank but it's still been brutal. All the sea urchins, starfish, scallops, shrimp, crabs, at least 40 of 50-60 snails, and some hermits are all dead. Along with that, nothing other than the fish have been eating. I've been pulling out the dead like never before, and it's even worse because nothing will eat them like what normally happens when something dies so they add even more poison to the tank. The tank is about 3 years old and potentially established. The reason I've posted this, however, is because of my carpet anemone.

Somehow when basically everything else died, it is still alive. It has looked like crap but is hanging in there. The problem now is that it looks really bad. Its curled up, has strings coming out of it, and is turning black and brown in some areas. I've been doing nearly daily 30% water changes with RO water since this happened (Sunday night). I've also added some reef safe AmQuell to help reduce all the ammonia and other things that are surely in the tank. Along with that I've added some stability (bacteria) since I'm sure lots was lost during the nuking. My question is what do I do with my nem? I've already accepted the fact that it will likely die, but I really would love to save it. I've had it for around 8 months. The real reason is because after 8 months, my clown finally took to it out of the blue and I've loved watching the symbiotic relationship. It's also kinda sad watching the clown desperately try to save the nem from dying. Also, if it does die, will the clown be more willing to take to another one? This is my first anemone and it took 7 months for this to happen, I doubt it makes a difference but I'd love for the relationship to continue. Thanks for any help!
 
why don't you remove the carpet and put it in a small 20gal QT. make some fresh salt water, put a nice clean LR inside, heater and a small powerhead. since that tank is dead/dying, use the light on the carpet. if you cant, place the tank next to a window. carpets are fairly clean animals so they shouldn't produce a lot of waste in the QT. not much cleaning needed if it's healthy.
 
What did he do exactly? What did he put in the tank that kill everything but not the fish? Copper? Soap? Other contaminant?

For now, take all things that living and put in a container. Wash all the rock in salt water to remove all dead stuff, set aside. If you have sand stirred up the sand to remove all dead animal in the sand (or remove the sand all together and add back a little at a time later when everything settle down). Change 100% of the water and put the rock back, wait for temp to stabilized and add all the animal and fish back.
You need to monitor the tank for cycle, hopefully it won't re-cycle. Do water changes need to keep ammonia down, and use AmQuell as needed.

m0nkie idea of put the carpet in QT/TT while everything settle down is a good idea. Clowns can go in there too if you don't feed them too much and do a lot of water change.
Best of luck
 
@orionN don't know if you'll agree but I think most likely a too great quantity of water changed with tap water containing copper and/ or fresh saltwater where salt hasn't had time to all dissolve and gives a false salinity reading therefore raising salinity too fast is most likely too kill all inverts and NOT fish !?


@Fish master13... Bill your dad for losses + quarantine your nem until everything is back to normal in your tank .
