Recovering from no power

[Pondweed]

My power went out last Tuesday, with me going on holidays on Thursday, power came back on late Saturday afternoon.

Lucky for me I still live close to home, I moved all fish, coral, rock & bio media over to my mums along with my spare tank + heaters. The fish are all okay, corals are looking a bit dodgy, but I think I can salvage most.

Question is, tank has been stagnant without water movement for maybe 2 days? I had a battery air pump on it but I am not sure when the batteries died

Still in the tank, sand + about 100ltr of water (and a few green mushroom corals that refuse to die) probably a boatload of dead pods + bristle worms.

Do I need to do anything to get this back up?

Just a syphon of the sand + big water change then bring up to temp and add everything back? I've got some bacteria starter as well so I can add that to maybe bring back some life in the sand

It will most likely have an ammonia spike from all the die off but that should cycle through. I would watch it for a few days just to be sure before adding back your live stock.
