If possible, you want to get the original tank back up and running as soon as possible then move the anemone back once the water has settled; your new tank will need more time to cycle.
What caused the crash? Just curious. Whatever it was, the great news is that you can fix it. You want to do large water changes for about a week then slowly tone things down the following week and the week after. Depending on how bad things are, I typically do about a 50% total volume water change daily for the first 3 days then I'll do 50% WC every other day for the next 4 days or so. From there, I just tone things down. Your nutrients will be down considerably but the toxins or whatever it was that cause the crash and whatever harm that was caused by the chain reaction will be down as well. Hopefully. you kept the tank because it's always a good idea to have a 2nd tank running in case you have an emergency.
From what I understand, Cipro is a medical treatment used for bacterial infections or chemical warfare. Although I'm not certain, you might not need to use it for now. Again, what caused the crash?
One of the first things I would do, is to get some good quality established live rock and add them to your new tank. You might already have enough bio but it doesn't hurt to up it a bit. Next, I would change the lighting spectrum to mostly blues. You want to go heavy on the UV and blue spectrums with moderate intensity using 0% whites, 0% green, and 0% red for now until the colors are back and even then, just keep it steady for a few more months until she's back to full health. The key is to make sure everything is gentle so try not to over dose the 2 part alkalinity and calcium, and whatever else you dose, and try not to over intensify the lighting.
If you choose to feed at this stage, same rule here, don't over feed. I think it was a good move to feed but if anything, you want to feed lightly because there's a difference between digestion and an anemone not accepting the food. When the anemone doesn't accept the food, it causes them to stress. It takes a few hours or sometimes longer for them to get back to its normal formation. When you compare this to an anemone that digest and swims in comfort, that's a big difference. Furthermore, you have to catch the food that is not accepted, otherwise, you'll have another set back, an ammonia spike. This is especially important thing to consider because your tank is new, so try to be careful with the feeding. I would try dropping 1 small Hikari marine carnivore pellet in there and hope it lands in the mouth. Try light feeding once or twice a week.
