Have you ruled out macroscopic pests yet? No flatworms or bugs?

I am 99.9% sure it’s not bugs lol

Well, Cipro isn't what I recommend for a marine tank anyways. If you're running any kind of lighting it's just useless. Under blackout conditions it may work alright.

So go with the amoxicillin? Lol

Just came across this thread after receiving an Aquabiomics test. Curious how things progressed?

I have done cipro whole tank dose twice but still have torches dropping one at a time oddly. I am now thinking maybe there is a solution in probiotics rather than anti. Trying PNS bacteria.

The trick to get around photodegredation of ciprofloxacin is to dose it at lights off. That way it will be at full strength over night until lights come back on in the morning.

The amoxicillin dosing recommended above (500 mg per 20 gallons) is very high. I actually tried this (detailed here: https://www.reef2reef.com/threads/sctld-last-resort-treatment.937152/ ) with near disastrous results. The dosing I currently recommend (for proven SCTLD) is 1-2 mg/gallon given daily for ten days.

In regards to what the OP was finding with his coral colonies dying no matter what he did, Acroporid White Syndrome (a disease with no known cause; see below) is definitely a possibility, but a diagnosis of exclusion. White Syndrome arrived in my system on an Indo mariculture colony and killed about 50 corals (including every example of certain species) before it settled down. No treatment was effective against it (and trust me, I tried all of them). I finally just let it run it's course and accepted my losses.

The Ecology of ‘Acroporid White Syndrome', a Coral Disease from the Southern Great Barrier Reef

Outbreaks of coral disease have increased worldwide over the last few decades. Despite this, remarkably little is known about the ecology of disease in the Indo-Pacific Region. Here we report the spatiotemporal dynamics of a coral disease termed ‘Acroporid ...

How rapidly does light effect these antibiotics? Seems like it does not take much at all. I kept mine in the fridge but not in a dark container so wondering if they were useless by the time I used them.

It's the combination of basic pH aqueous solution and blue spectrum light that rapidly degrades ciprofloxacin, so you're probably fine.
