You’ll have plenty of time to scoop your fish out. The corals will be fine.Forgot to ask how long do I have once I start draining the water? In terms of no flow or no water circulation? Debating on removing at least some of the rock in case plan a gonna go south. Problem is it’s all standing on 3 rocks which are silicones to glass and balances on fiber sticks and a bunch of glue and more silicone. If it starts swinging sideways. I already had so many close calls. And top glass braces are 8 inches wide and there are 4 of them. Plus cabinets blocking 12 inches of entire back tank. So half the tank is blocked by glass bracing and half in cabinets. Complete nightmare in this case. I wasn’t planning on taking it apart
Don’t worry about dipping/QT the corals/inverts. Parasites cannot reproduce on them. They are equivalent to a rock. They can hold the eggs, but the 45 day fallow will kill all the parasites.
